Supertex inc.HV9910BDB7HV9910B PFC 40W LED Driver DemoboardSpecificationsActual Size: 3.0” x 2.3” x 1.1”Top View Bottom ViewGeneral DescriptionThe Supertex HV9910BDB7 demonstrates the use of an HV9910B control IC in an off-line, High Brightness LED driver application. The board incorporates power factor correction (PFC) and satisfies the limits for harmonic currents according to the EN61000-3-2 Class C standard having total harmonic distortion (THD) less than 20%. The board features a low component count and long life operation due to the absence of electrolytic capacitors. The board is designed to supply a string of LEDs with a current of 350mA and a voltage in the 65 to 105V range from a 220/230VAC line.The conversion stage draws line current throughout the AC line cycle, partly using a charge pumping and partly using a boost conversion technique to charge the bulk energy storage capacitors. The LED current is provided with a continuous mode buck stage giving a DC current with about 30% peak-to-peak ripple. A patent for this conversion technique is pending. Please inquire with the Supertex applications department for design guidance, should change of input line voltage, output voltage, or output current be desired.An effort was made to satisfy the requirements of CISPR 15 (EN55015), limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment.The connection diagram details the hookup of the board to the AC line. Note that the load is NOT galvanically isolated, and that measurements to the board require measurement techniques in common use with non-isolated off-line power supplies (isolation transformers, differential probes, etc).Board LayoutSchematic DiagramConnection Diagram220VAC105VDC 350mADCConnectionsI nput Voltage - Connect the AC line input voltage to AC VIN as shown.LED String - Connect the LED strings between LED+ and LED- as shown (anode of the string to LED+ and cathode to LED-).Figure 3.

本文将以Supertex的以HV9911为例,来提供读者升压式高亮度LED背光驱动电路设计的相关讯息。
■升压电路设计特色 升压电路是用来驱动LED的串联电压高于输入电压(图1),并且有以下的特色: 1.此电路可被设计在效率高于90%下操作。
2.M=S FET的(Source)与LED串共地,这简化了LED电流的侦测(不像降压电路必须选择上侧FET驱动电路或上测电流侦测。
但是升压电路也有些缺点,特别是用于LED驱动,由于LED 串的低动态阻抗)。
3.输入电流是连续的,使得输入电流的滤波变得简单许多(并更容易符合传导式EMI标准的要求)。
4.关闭用的FET毁损不会导致LED也被烧毁。
5.升压电路的输出电流为脉冲式波形,因此,必须加大输出电容以降低LED串的涟波电流。
6.但是过大的输出电容,使得PWM调光控制变得更具挑战,当控制升压电路开与关,以达到PWM调光控制,就表示输出电流会被每一个PWM调光控制周期充放电,这使得LED串电流的上升与下降时间会拉大。
超特克(Supertex)MD1812和MD1813芯片应用说明书

Supertex inc.AN-H56Application NoteIntroductionThe MD1812 and the MD1813 are two unique composite return-to-zero (RTZ) pulser drivers for ultrasound applications. The ICs have built-in level shifters that provide negative P-MOS gate DC bias and fast AC coupled gate drivesignals. They enable the fast damping functions necessary to generate return-to-zero bipolar pulses, and are also able to keep the zero-state to as long as needed, even to infinity. These kinds of fast return-to zero and DC coupled features are very useful for medical ultrasound imaging equipment, piezoelectric transducer drivers, material flaw detection, ultrasonic NDT detection, and sonar ranger applications, especially for those that need to launch ultrasound in pseudo-random codes. Designing a Pulser with the MD1812/13This a pplication n ote d escribes h ow t o u se M D1812 o r M D1813 to design the basic channel of an ultrasound transmitter with the RTZ feature. The circuit is a single channel ultrasound transmitter using the MD1812 or MD1813 to drive TC6320 & TC2320 MOSFETs. It can generate fast return to zero waveforms. The output of high voltage to transducer has ±2A source and sink current capability. A CPLD programmable logic circuit and on-board 40MHz crystal oscillator generate a fast logic signal to control the pulse circuit. The CPLD hasa six-pin JTAG connection for Xilinx’s USB or a convenient parallel-port programming link cable. The circuit consists of one MD1812K6 or MD1813K6 in a 16-lead 4x4x0.9mm QFN package, driving TC6320FGs and TC2320FGs, two complementary high-voltage P and N- channel MOSFETs in one single SO-8 package. The input stage of the MD1812/13 is a high-speed level translator that is able to operate with logic input signals of 1.2V to 5.0V amplitude. In this circuit, the CPLD output logic is typically 3.3V. An adaptive threshold circuit is used with the OE pininside of the MD1812 to set the level translator threshold to the middle of the input logic 0 and logic 1 levels. The OE pin serves a dual purpose. First, its logic 1 level is used to compute the threshold voltage level for the channel input level translators. Second, when OE is low, the outputs are disabled, with the A and C outputs high and the B and Doutputs low (for MD1812 only). This assists in properly pre-charging the coupling capacitors that may be used in series in the gate drive circuit of external PMOS and NMOS FETs. The MD1812/13 level translator uses a proprietary composite drive circuit, which provides DC coupling, together with high-speed operation. The output pin, OUT C , is designed to drive the return-to-zero PMOS FET through a capacitor as fast as an AC coupling gate driver, and OUT G provides delayed DC coupling negative biased gate control to the same PMOS FET. The OUT C swings between V H and V L voltages, while OUT G is within V SS or V NEG levels. Note that the OUT C and OUT G pins of one chip are designed to drive together forone PMOS FET, and that the PMOS FET source is typicallyconnected to the same potential of the MD1812/13 V SS voltage. Each of the output stages of OUT A , OUT B , OUT C & OUT D of MD1812/13 are capable of peak currents of up to ±2.0A, depending on the supply voltages used and load capacitance. But a 2kΩ resistor, R36, must be between OUT G and the gate of the PMOS FET, which is driven by the OUT C through a capacitor. This configuration provides the optimal series resistance value of the gate DC bias driver circuit.The output stage of the MD1812/13 has separate power connections enabling the output signal high and low levels to be chosen independently from the driver supply voltages. As an example, the input logic levels may be 0V and 1.8V, the control logic may be powered by +5V and –5V, and the output high and low levels may be varied anywhere over the range of +5V to -5V. In this design example, MD1812/13’s V DD and V H are both powered by +10V, V SS and V L are grounded, and V NEG is –10V. The source pin of the RTZ PMOS FET driven by the OUT C and OUT G pins is connected to ground.PCB Layout TechniquesIt is very important that the slab at the bottom of the IC package, which is the IC substrate “pin”, be externally connected to the V NEG pin to make sure it always has the lowest potential in any condition.Designing An Ultrasound Pulser with MD1812/MD1813 Composite DriversBy Ching Chu, Sr. Application EngineerUse high-speed PCB trace design practices that are compatible with the circuit’s operating speed. The internal circuitry of the MD1812/13 can operate at up to 100MHz, with the primary speed limitation being due to load capacitance. Because of this high speed and the high transient currents that result when driving capacitive loads, the supply voltage bypass capacitors should be as close to the supply pins as possible. The V SS and V L pins should have low inductance feed-through connections that are connected directly to a solid ground plane. If these voltages are not zero, they will require bypass capacitors similar to the positive power supplies. The V DD and V H supplies determine the output logic levels. These two pins can draw fast transient currents of up to 2.0A, so they should be provided with a low-impedance bypass capacitor at the chip’s pins. A ceramic capacitor of up to 1.0µF may be appropriate. Minimize the trace length to the ground plane, and insert a ferrite bead in the power supply lead to the capacitor to prevent resonance in the power supply lines. A common voltage source and local decoupling capacitor may be used for the V DD and V H pins, which should always have the same DC level applied to them. For applications that are sensitive to jitter and noise, insert another ferrite bead between V DD and V H and decouple each pin separately.Pay particular attention to minimizing trace lengths and using sufficient trace width to reduce inductance. Surfacemount components are highly recommended. Since the output impedance of this driver is very low, in some cases it may be desirable to add a small value resistor in series with the output to obtain better waveform integrity at the load terminals. This will, of course, reduce the output voltage slew rate at the terminals of a capacitive load. Pay particular attention to the parasitic coupling from the driver’s output to the input signal terminals. This feedback may causeoscillations or spurious waveform shapes on the edges of signal transitions. Since the input operates with signals down to 1.2V, even small coupling voltages may cause problems. Use of a solid ground plane and good power and signal layout practices will prevent this problem. Also ensure that the circulating ground return current from a capacitive load cannot react with common inductance to create noise voltages in the input logic circuitry.Testing the Ultrasound Pulser The MD1812 RTZ pulser design example is tested with the following power supply voltage and current limiting: V PP 0 to +100V 5mA, V NN 0 to -100V 5mA, V DD = +10V 50mA, V NEG -10V 5mA, V CC +3.3V, 90mA.The HV OUT signal appears at the SMA connector J6. There is a 5:1 attenuation of the signal, due to the value of resistor R11. When driving a real transducer load, the value of this resistor should be reduced in value to match the load impedance.The HV OUT signal passes through jumper J5, which can be used to terminate the HV OUT signal in a dummy load, comprising a 220pF capacitor in parallel with a 1kΩ resistor. When an external load is connected, the dummy load is not required, and J5 can be configured to pass the signals straight through to the output connector J6.All the on-board test points are designed to work with an active oscilloscope probe, such as the Tektronix P6243 1MΩ active probe. Because TP7 is connected to the HV OUT , where potentially damaging voltages could be present, make sure that V PP /V NN does not exceed the probe limit. If using another type of high impedance oscilloscope probe for the test points, ensure that the ground lead connections to the circuit board ground plane are as short as possible.There are multiple frequency and waveform combinations that can be selected as bipolar pulses, PW or CW waveforms. An external clock input can be used if the on-board 40MHz-oscillator is disabled. The external trigger input can be used to synchronize the output waveforms. There are five push buttons for selecting demo waveform, frequency, phase, and MD1812 chip enable functions. Color LEDs indicate the demo selection states. The CH1 output allows the monitoring of one of the 5 inputs (IN A , IN B , IN C , IN D or O E ) of the MD1812/13 via the select button. The MD1812 and the MD1813 are very similar in function. The only differences between them are the control of the OE (MD1812) vs VLL (MD1813) pin and their logic functions. Please read their data sheets for the details. In this design example, the CPLD program is using an on-board solder jumper, R34, to sense the difference and works accordingly.

They have been optimized for a variety of applications and may be used as is or used as a starting point in designing a circuit for a particular application.When constructing and testing one of the driver circuits listed below, keep in mind that results may differ from those given due to component tolerances and lamp characteristics. When making component changes, always remove supply voltage first. After making adjustments, bring up the supply voltage slowly (starting from the minimum required device input voltage) while monitoring input current. Excessive input current may be a good indication of connection errors or incorrect component values. A sharp rise in current usually indicates a saturated inductor. To avoid inductor saturation, use a higher current rated inductor or increase the conversion frequency by lowering the RSWresistor value.Notes:1.

超图电子HV9861ADB1高光LED驱动板说明书
Supertex inc.HV9861ADB1General DescriptionThe HV9861ADB1 demoboard is a high-brightness LED driver employing the patented average-mode, constant current control scheme by Supertex Inc. The power conversion stage of the HV9861ADB1 consists of a diode bridge rectifier followed by a buck converter operating with fixed off-time of 20µs.The HV9861ADB1 LED driver features tight regulation of the LED current within a few milliamps over the entire range of the input AC line and the output LED string voltage. The LEDcurrent accuracy is almost insensitive to the passive component tolerances, such as the output filter inductance or the timing resistor. The accuracy of the LED current is mainly determined by the internal 270mV ± 3% reference voltage of the HV9861A control IC and by the external current sense resistor tolerance.(Note, that the linear dimming input of the HV9861A disables switching, when its voltage falls below a 200mV threshold.Expect the LED driver to shut off when the LED current falls below 50 ~ 55mA.)PWM dimming can be achieved by applying a pulse-width-modulated square wave signal between the PWMD and GND pins.The HV9861ADB1 features protection from an output short circuit condition. Open LED protection is inherent, since theoutput filter capacitor can accept the full rated rectified AC line voltage. Please, note that the demoboard is not CISPR15 compliant.An additional input EMI filter circuit is required to make the board meet conducted electro-magnetic emission limits. Also, note that:NO SAFETY ISOLATION OF THE LED LOAD FROM THE AC MAINS VOLTAGE IS PROVIDED!21-Watt, Universal, AC LED Driver Demoboard with Accurate Average-Mode, Constant Current ControlConnection Diagram WARNINGDo not connect earth-grounded test instruments. Doing so will short the AC line, resulting in damage to the instrument and/or the HV9861ADB1. Use floating high voltage differ -ential probes or isolate the demoboard by using an isolat-ing transformer.No galvanic isolation. Dangerous voltages are present when connected to the AC line.1. Connect the input AC voltage between the AC INterminals as shown in the connection diagram.2. Connect the LED string between LED+ (anode ofLED string) and LED- (cathode of LED string).3. Connect the PWMD terminal to the VDD terminalusing the jumper provided to enable the LED driver.4. The current level can be adjusted by applying 0 -1.5V between LD and GND. Leave LD floating to use the internal current setting.Connections90-265VAC50/60Hz0 -1.5V for LD function or leave openSilk ScreenPWM DimmingThe HV9861ADB1 is capable of being PWM dimmed by apply-ing a square wave TTL compatible signal between PWMD and GND terminals. However, since there is no galvanic isolation on the board, care must be taken to prevent damage to the PWM dimming source and/or the HV9861ADB1. One simple way is to isolate the LED driver from the AC line using an isola-tion transformer. Another approach is to use an opto-isolator to drive the PWMD pin as shown in the following figure.5.0Vsquarewavesignal(<1.0kHz)PWMDVDD(e.g. LTV-814 from Lite-On) Schematic60L E D C u r r e n t (A )AC Line Voltage (VAC)AC Line Voltage (VAC)L E D C u r r e n t (A )PWM Dimming Response Short Circuit CurrentI LEDPWMDV IN = 240VACTypical CharacteristicsSupertex inc. does not recommend the use of its products in life support applications, and will not knowingly sell them for use in such applications unless it receives an adequate “product liability indemnification insurance agreement.” Supertex inc. does not assume responsibility for use of devices described, and limits its liability to the replacement of the devices determined defective due to workmanship.

Supertex inc.AN-H59Application NoteApplication CircuitHigh Voltage DC/DC Converter forSupertex Ultrasound Transmitter DemoboardsBy Afshaneh Brown, Applications Engineer,and Jimes Lei, Applications ManagerIntroductionThe Supertex AN-H59DB1 demoboard is a high voltage DC/DC converter. It can provide up to +90V voltage supply for V PP and -90V for V NN . It also provides +8.0 to +10V voltage supply for V DD , floating power supplies of V NN +8.0 to V NN +10V for V NF and V PP -8.0 to V PP -10V for V PF . The input supply voltage is 12V.The AN-H59DB1 circuitry consists of two high voltage PWM Current-Mode controllers, a DC/DC transformer driver, and three low dropout regulators. The Supertex AN-H59DB1 uses a high-voltage, current mode, PWM controller boost topology to generate +15 to +90V and a high-voltage current mode PWM controller buck-boost topology to generate -15 to -90V power supply voltage for Supertex HV738DB1 and HV748DB1 ultrasound transmitter demoboards.Each of the transmitter demoboards has slightly different operating voltages as summarized below.To accommodate all three demoboards, the AN-H59DB1 demoboard has adjustable V PP , V NN , V DD , V PF and V NF . The purpose of the AN-H59DB1 is to aid in the evaluation of the three transmitter demoboards. The intention of this application note is to provide a general circuit description on how each of the output voltages is generated.The VSUB pin on the HV738DB1 and HV748DB1 can either be connected to the most positive supply voltage on the demoboard, or can be left floating.To power up the AN-H59DB1, ensure that the 3.3V power supply will be powered up first, and then the 12V power supply. The sequences on the HV738DB1 and HV748DB1 took into consideration using the protection diodes on each power line.The circuit is shown in Figure 6, the component placement in Figure 5, and the bill of materials is at the end of thisapplication note.PP The circuit in Figure 1 shows U5, the Supertex high volt -age current mode PWM controller, being used to generate the high voltage power supply for V PP . The maximum output power for V PP was set for 10mA at 90V, which is 900mW. With an input voltage of 12V, a converter frequency of 110 kHz with a 100µH inductor was chosen to provide the de -sired output power.The converter frequency is set by an external resistor, R20, across OSC IN and OSC OUT pins of U5. A 154kΩ resistor will set the frequency to about 110 kHz. R24 is the current sense resistor. 2.2Ω was used to set the maximum peak current limit to about 450mA. An RC filter, R23 and C15, is added between the current sense resistor and the current sense terminal pin 3 of U5. This reduces the leading edge spike on R24 from entering the current sense pin.Inductor L1 is being charged from the 12V input by M3. When M3 turns off, the energy in L1 is discharged into C16, which is the V PP output through D8. The V PP voltage is di-vided down by feedback resistors R25, R26, and R27. The wiper of R26 is connected to pin 14 of U5. The overall con -verter will regulate the voltage on pin 14 to 4.0V. Different V PP output voltages can be obtained by adjusting R26.When the wiper for R26 is set to the top, V PP can be calcu-lated as:where V FB is 4.0VWhen the wiper for R26 is set to the bottom, V PP can be calculated as:By adjusting potentiometer R26, V PP meets the adjustable target range of 15 to parator U6 will turn on LED D7 when the V PP output is out of regulation due to excessive load. During initial power up, C16 will be at 0V. D7 is therefore expected to be on until C16 is charged to the desired regulation voltage.Figure 1: Adjustable V PP Power SupplyV PPGNDV PP = 4.0V x ( 232k + 100k + 14.3k )= 12.1V 100k + 14.3k V PP= V FBx ( R25 + R26 + R27 )R26 + R27V PP = 4.0V x ( 232k + 100k + 14.3k )= 96.9V 14.3kV PP = V FBx ( R25 + R26 + R27 )R27NN The circuit in Figure 2 shows U7, the Supertex high voltage current mode PWM controller, being used to generate the high voltage power supply for V NN . The function of U7 is very similar to what was described in the V PP circuit description for U5. However, in this circuit a negative voltage is gener -ated from a positive input voltage source, therefore requir-ing a buck-boost topology. The maximum output power for V NN was set for -10mA at -90V which is 900mW. With an input voltage of 12V, a converter frequency of 110 kHz with a 100µH inductor was chosen to provide the desired output power.Inductor L2 is being charged from the 12V input by the par-allel combination of M6 and M7. When M6 and M7 turn off, the energy in L2 is discharged into C23, which is the V NNoutput through D10. M6 and M7 are high voltage P-channel MOSFETs. U7 is designed to drive a high voltage N-chan -nel MOSFET. The drive output for U7 therefore needs to be inverted. This is accomplished by M4 and M5.The feedback voltage that U7 detects on pin 14 is +4.0V. The V NN that needs to be sensed is a negative voltage. A cir-cuit is needed to make sure the feedback voltage is positive. This is consists of Q4, Q5, R33, R34, R35, R37, and R38. Q4 becomes a constant current sink set by the V NN voltageand R35. The same current will be flowing through R33 and R34.The voltage on the base of Q5 will be V IN minus the voltage drop across the sum of R33 and R34. By varying R34, the base voltage on Q5 will change. Q5 becomes a constant current source with a value set by its base voltage and R37. The current source of Q5 is going into R38, which creates a positive voltage that is now proportional to the magnitude of V NN .where V BE = 0.6V, V FB = 4.0V.When R34 is set to 100k, V NN is calculated to be:= -4.0VWhen R34 is set to 0k, V NN is calculated to be:= -97.4V By adjusting potentiometer R34, V NN meets the adjustable target range of -15 to parator U8 will turn on LED D9 when the V NN output isout of regulation due to excessive load. During initial power up, C23 will be at 0V. D9 is therefore expected to be on until C23 is charged to the desired regulation voltage.Figure 2: Adjustable V NN Power SupplyVNN-15V to -90V GNDV NN = V BE - ( R35 ) x (V BE + V FB x R37 ), R33 + R34 R38V NN = 0.6V - ( 273k) x (0.6V + 4.0V x 14.7k ) 4.99k + 100k 40.2k V NN = 0.6V - ( 273k ) x (0.6V + 4.0V x 14.7k )4.99k + 0k 40.2kVPF and VNF Circuit DescriptionThe three transmitter demoboards require two floating low voltage supplies, V PF and V NF . The floating supplies need to be adjustable to accommodate the different operating re-quirements for the three different boards. The V PF is 8.0 to 10V below the high voltage V PP positive supply. The V NF is 8.0 to 10V above the high voltage V NN negative supply. The two floating supplies are generated by using two isolated transformers, T1 and T2, and an isolated transformer driver, U1, as shown in Figure 4. Both outputs utilize adjustable low dropout linear regulators, U2 and U3, as shown in Figure 3. U2 and U3 are both Linear Technology LT1521, which has a reference voltage of 3.75V on the ADJ pin. For V PF , resistors R6, R7, and R8 set the output V PF voltage. R7 is a potentiom -eter for adjusting V PF . V PF can be calculated with the following equation:When R7 is set to 20kΩ, V PF becomes:When R7 is set to 0Ω, V PF becomes:Please note that the OUT pin on U2 is referenced to V PP , thereby setting V PF to be 8.0 to 10V below V PP . V NF can also be calculated in a similar manner using resistors R12, R13, and R14. Please note that the GND pin on U3 is referenced to V NN thereby setting V NF to be 8.0 to 10V above V NN .LED indicators, D5 and D11, start to turn on when the input current to U2 and U3 reaches an arbitrary value of 40mA. This is set by Q1 and R3 for V PF and Q2 and R9 for V NF . The input current can be calculated with the following equation: Input current = V EB = 0.5V = 41.3mA R 12.1Ω50mA current limits are added to protect against output shorts. The current limiter is consists of a depletion-mode MOSFET and a series source resistor. The resistor sets the current limit and can be estimated with the following equa -tion:R SERIES = V TH x ( √I LIM / I DSS - 1) where, I LIMV TH = pinch-off voltage for M1 and M2: -2.5V I LIM = desired current limit: 50mAI DSS = saturation current for M1 and M2: 1.1A R SERIES = 39.3Ω. A 40.2Ω resistor was used.Figure 3: Adjustable V PF and V NF Power SupplyV VNFVFPV PF = 3.75V x ( 45.3k + 20k + 24.9k )= 7.53V 20k + 24.9kV PF = 3.75V x ( 45.3k + 0k + 24.9k )= 10.6V 0 +24.9kV PF= V ADJx ( R6 + R7 + R8 )R7 + R8V DD Circuit DescriptionThe V DD output voltage utilizes an adjustable low dropout lin -ear regulator, U4 LT1521, as shown in Figure 4. The desiredadjustable output voltage range is 8.0 to 10V to accommo-date the different operating V DD voltages for the three differ-ent transmitter demoboards.The LT1521 has a reference voltage of 3.75V on the adj pin. Resistors R17, R18, and R19 set the output V DD voltage. R18 is a potentiometer for adjusting V DD . V DD can be calcu-lated with the following equation:When R18 is set to 20kΩ, V DD becomes:When R18 is set to 0Ω, V DD becomes:An LED indicator, D6, is included in case of excessive input,I IN, current. D6 is starts to turn on when the input currentreaches an arbitrary value of 20mA. This is set by Q3 and R15. When the emitter-base junction of Q3 is forward biased (0.5V), Q3 will start to turn on, thereby forward biasing D6.The I IN value to turn D6 on can be calculated with the follow -ing equation: I IN = V EB = 0.5V= 20.6mAR1524.3Ω 3.3V Input TerminalThe AN-H59DB1 has a 3.3V input terminal that is directly connected to the output terminal, V CC . There is no circuitry on this board that uses the 3.3V supply. It is only there as a convenient connection to the 8-pin header. V CC is the logic supply voltage for HV738DB1 and HV748DB1 and can oper-ate from 1.2 to 5V. However, most users will operate V CC at either 3.0 or 3.3V.Input and Output PowerThe output voltages from the AH-H59DB1 are all generated from the 12V input line. With no load on the outputs, the measured input current was about 70mA. This input current can vary from board to board due to variations in the isolated transformer.The maximum output power is:P OUT(MAX) = P VPP(MAX) + P VNN(MAX) + P VPF(MAX) + P VNF(MAX) + P VDD(MAX)P OUT(MAX) = 0.9W + 0.9W + 0.4W + 0.4W + 0.2W P OUT(MAX) = 2.8WUnder this condition, the 12V input current was measured to be 340mA. Input power is therefore 4.08W. This gives an approximate overall efficiency of 69% at full load.Figure 4: Adjustable V DD Power SupplyV IN = 12VVDD+8.0 to 10V GNDV DD = 3.75V x ( 45.3k + 20k + 24.9k )= 7.53V20k + 24.9kV DD = 3.75V x ( 45.3k + 0k + 24.9k )= 10.6V 0 + 24.9k V DD = V ADJ x ( R17 + R18 + R19 )R18 + R19VPF and VNF Output CurrentThe AN-H59DB1 can supply more than 40mA of current for the V PF and V NF outputs. The I NF and I PF input currents for the HV738 or the HV748 can be found in their respective datasheet but are summarized below:This is for continuous 5.0 MHz operation. For ultrasound, thehigh voltage transmitter is operating at very low duty cycles; 1% or lower. At a 1% duty cycle, the average current is ex -pected to be a 100 times lower. The 40mA output current ca -pability on the AN-H59DB1 is more than sufficient to power up the HV738 or the HV748.ConclusionThe main purpose of AN-H59DB1 power supply demoboard is to help the evaluation of the Supertex HV738DB1 and HV748DB1 demoboards by reducing the number of power supplies needed. The AN-H59DB1 was designed to operate from a single 12V input which should be commonly available in any engineering laboratory.The five on-board LEDs allow the user to quickly determine whether there is an overload condition on each of the supplylines. The five potentiometers allow the user to easily adjust each supply to meet their particular needs.Figure 5: AN-H59 Component PlacementFigure 6: AN-H59 Circuit SchematicVPPVPFVNFSupertex inc. does not recommend the use of its products in life support applications, and will not knowingly sell them for use in such applications unless it receives an adequate “product liability indemnification insurance agreement.” Supertex inc. does not assume responsibility for use of devices described, and limits its liability to the replacement of the devices determined defective due to workmanship.
