在管脚HV 电压上升时，DD V 电容（VDD C ）通过一个内部的结型场效应管电流源充电。
直到管脚DD V 上的电压上升到DD V =)(start DD V ，启动电流源被禁用。
此时，半桥开始工作，DD V 电源改由充电泵供电。
DD V 流过的电流值等于HV DVDT V C f ××,f 为瞬时频率。
充电泵由外部半桥电容(DVDT C )、两个内置（只对于SO14封装）二极管和一个内置的齐纳二极管组成。
对于DIP8封装，这些二极管需要外接。
齐纳二极管保证DD V 电压不会超过最大DD V 额定值。
DVDT 电源含有自身的接地管脚(PGND)，可以防止由外部小信号低（SGND）上产生的峰值电流影响。
启动电流源在管脚DD V 电压小于()stop DD V 时会再次工作。
当DD V 引脚上电源电压增加,IC进入启动阶段。
在启动阶段，上桥功率晶体管关断，下桥功率晶体管导通。
内部电路复位，引脚FS上的自举电容和低压电源引脚DD V 上的电容被充电。
引脚RC和SW对地短接。
当DD V 脚上电压大于)(start DD V ，系统退出启动阶段进入预热阶段。
如果DD V <)(stop DD V ，系统将回到启动状态。
注意：如果过温保护（OTP）被激活，只要该状态一直存在，IC将会维持在启动状态。
DD V 电压将会在)(stop DD V 和)(start DD V 之间缓慢振荡。
7.3复位上桥驱动电路中集成了DC复位功能。
当引脚FS上的电压低于上桥自锁电压时，上桥晶体管关断。
7.4振荡控制振荡频率基于555定时器功能实现。
利用外部电阻器osc R ，SENSE R 和电容器osc C ，实现一个自振荡电路，osc R 和osc C 决定振荡频率。
为了实现精确的50％占空比，在内部使用了一个分频电路。
该分频电路能将半桥频率设置为振荡器频率的一半。
管脚SW的输入产生信号SW V ，它决定了除预热阶段以外的所有阶段的频率，()ph SW V 是内部产生的信号，决定预热阶段的频率。
半桥输出电压在管脚RC信号的下降沿处改变。
半桥正常工作频率如式1所示：()1OSC nom OSC OSC OSCf k R C =×× (1)最大频率为2.5OSC f ×,通过SW V 来设置。
图4中给出了振荡器信号、内部LS 和HS 驱动信号、以及输出信号的对应时序波形。
图4：振荡器，HSPT/LSPT 驱动和输出信号7.5预热阶段7.2节中提到，当管脚电压(start)DD DD V V >且未触发OTP 时，IC 进入预热阶段。
管脚SW 上的电容（SW C ）由SW I 充电，内部的运算放大器(OTA)被激活状态，半桥电路开始振荡。
通过外部电阻SENSE R 来检测预热电流。
OTA 通过输出电压(ph)SW V 来控制频率，这样，SENSE R （例如：在LS 最后导通期间的电压）上的峰值电压等于内部参考电压(ph)ref V 。
流经灯丝的预热电流参见式2：()()r e fp h p h p e a k S E N S EV IR =（2）预热时间由外部电容SW C 决定。
当SW C 的电压降至(ph)SW V ，预热阶段结束。
（见图4） 如果在预热阶段，检测到了电容模式（比如当灯的电极被破坏，灯的寿命终止），振荡器就会停止工作，内部SW V 的HIGH 结点放电，频率重新从max f 开始扫描。
图5：()OSC nom f 、SW V 、(prht)SW V 、lamp V 随时间变化曲线7.6点火阶段预热结束后，芯片进入点火阶段。
SW 脚上电容（SW C ）被SW I 进一步被充电到0.6×()RC H V ，此时频率达到sc(nom)o f 。
在扫频期间，当频率达到谐振频率时，便产生一个让灯正常点火的高压脉冲（见图4）。
谐振频率由灯的电感和电容设定。
当SW 脚上电压达到0.6×()RC H V 后，芯片结束点火阶段。
7.7稳定运行阶段在稳定运行阶段，RMS 电流控制处于工作状态。
通过设定频率值使SENSE R 上的RMS 电压等于()RMS ref O V ，维持恒定的功率开关（和灯）上的RMS 电流。
在恒定的室温下，IC 的损耗和IC 的温度都会保持不变。
在一个振荡器周期内，管脚SENSE(SENSE V )上的电压被平方，转换成正向电流，此（放电）电流对电容SW C 进行放电。
在下一个振荡器周期里，平方器输入端与内部参考电压()RMS ref O V 连接。
这个电压被平方，转换成一个反向电流。
此电流（充电）对电容SW C 进行充电。
当正电流和负电流相等时，式3成立：()()22011oscoscT T SENSE t DTO ref RMS DToscoscVV T T ×=×∫∫ (3)其中：1osc OSC T f =两边开方的式4：= （4）或：()SENSE SENSE LSPT O ref RMS RMSV V R I ==× （5）这样，通过内部参考电压()RMS ref O V 和外部SENSE R 电阻，便能将功率开关和灯电流确定为恒定值。
7.8死区时间死区时间为两个MOSFET 都未导通的时间，死区时间是内部固定的。
7.9过热保护(OTP)所有阶段都可能激活过热保护。
当温度达到OTP 激活阈值温度（()otp act th T ）时，振荡器停止工作，功率开关（LSPT/HSPT）设定在启动状态。
当振荡器停止工作时，DVDT 电源将不会提供电流DVDT I 。
电压DD V 将会逐渐减小，当DD V <）（stop DD V 时，进入启动阶段，如7.2节所述。
当T<()otp rel th T 时，OTP 被复位。
7.10最小辉光时间控制如果预热时间设定得太短或完全没有，点火时灯电极就不能处于合适的温度。
这可以瞬时点亮，但电极温度较低时会导致电极飞溅和损坏，同样也会降低开关的使用寿命，在辉光阶段，使用一个专用的控制来提供最大功率，使得电极可以尽快被加热（见图6）。
这样可以将对电极的危害降至最低。
图6：()OSC nom f 、SW V 、(ph)SW V 、lamp V 随时间的变化曲线。
电极预热时间ph t 太短时就会启动辉光时间控制7.11饱和电流保护灯电感设计中的关键参数即为饱和电流。
当电感的瞬时电流超过饱和值，电感量会迅速降低。
结果电感电流（即流经功率开关LS 和HS 的电流）迅速上升并可能超过半桥功率晶体管的最大额定值。
在考虑降低成本和缩小CFL 体积时，可能发生灯电感饱和的情况。
UBA2211能检测功率晶体管的电流。
当电流超出半桥功率晶体管的瞬时应力，IC 会缩短晶体管的导通时间并且频率会缓慢增高（通过对SW C 放电）。
这样系统就会平衡电流，让内部功率开关工作在其所能承受电流应力的边缘而不至于损坏。
7.12电容模式保护当检测到电容模式时，电容SW C 被放电，导致频率上升。
系统会设置自身工作点，使电容模式开关损耗在最小状态。
这种电容方式在点火阶段和稳定阶段起作用。
当电容模式在预热阶段被检测时，振荡器从频率max f 启动。
当灯丝损坏导致灯寿命终止时，会触发电容模式保护。

Placing a high-value electrolytic capacitor on the input (10-μF minimum) and output pin(s) is recommended when the output load is heavy. This precaution reduces power-supply transients that may cause ringing on the input. Additionally, bypassing the output with a 0.01-μF to 0.1-μF ceramic capacitor improves the immunity of the device to short-circuit transients.Over-current and Short Circuit ProtectionAn internal sensing FET is employed to check for over-current conditions. Unlike current-sense resistors, sense FETs do not increase the series resistance of the current path. When an overcurrent condition is detected, the device maintains a constant output current and reduces the output voltage accordingly. Complete shutdown occurs only if the fault stays long enough to activate thermal limiting.Three possible overload conditions can occur. In the first condition, the output has been shorted to GND before the device is enabled or before V IN has been applied. The AP2101/AP2111 senses the short circuit and immediately clamps output current to a certain safe level namely I LIMIT.In the second condition, an output short or an overload occurs while the device is enabled. At the instance the overload occurs, higher current may flow for a very short period of time before the current limit function can react. After the current limit function has tripped (reached the over-current trip threshold), the device switches into current limiting mode and the current is clamped at I LIMIT.In the third condition, the load has been gradually increased beyond the recommended operating current. The current is permitted to rise until the current-limit threshold (I TRIG) is reached or until the thermal limit of the device is exceeded. The AP2101/AP2111 is capable of delivering current up to the current-limit threshold without damaging the device. Once the threshold has been reached, the device switches into its current limiting mode and is set at I LIMIT.To protect against short circuit to GND at extremely low temperature (< -30o C), a minimum 120-μF electrolytic capacitor on the output pin is recommended. A correct capacitor type with capacitor voltage rating and temperature characteristics must be properly chosen so that capacitance value does not drop too low at the extremely low temperature operation. A recommended capacitor should have temperature characteristics of less than 10% variation of capacitance change when operated at extremely low temp. Our recommended aluminum electrolytic capacitor type is Panasonic FC series.At low input voltage condition (V IN < 3V), the short circuit protection current may rise as high as twice the typical value.FLG ResponseWhen an over-current or over-temperature shutdown condition is encountered, the FLG open-drain output goes active low after a nominal 7-ms deglitch timeout. The FLG output remains low until both over-current and over-temperature conditions are removed. Connecting a heavy capacitive load to the output of the device can cause a momentary over-current condition, which does not trigger the FLG due to the 7-ms deglitch timeout. The AP2101/AP2111 is designed to eliminate false over-current reporting without the need of external components to remove unwanted pulses.Power Dissipation and Junction TemperatureThe low on-resistance of the internal MOSFET allows the small surface-mount packages to pass large current. Using the maximum operating ambient temperature (T A) and R DS(ON), the power dissipation can be calculated by:P D = R DS(ON)× I2分销商库存信息:DIODESAP2111SG-13AP2101MPG-13AP2101SG-13 AP2111MPG-13。

OB2211, OB2212 Datasheet
GENERAL DESCRIPTIONOB2211/OB2212 series is an offline PWM Power switch for low power AC/DC charger and adaptor applications. It operates in primary-side sensing and regulation, thus, opto-coupler and TL431 is eliminated. It achieves excellent Constant Voltage (CV) and Constant Current (CC) performance by built-in constant current and constant voltage control, as shown in the figure below. OB2211/OB2212 operates with flyback converter in DCM mode. The pulse frequency modulation (PFM) is used in CC control. In CV control, multi-mode operations are utilized to achieve high performance and efficiency: fixed frequency mode at large load conditions; frequency reduction mode atlight/medium load; ‘Extended burst mode’ atNo/light load. OB2211/OB2212 offers complete protection coverage with auto-recovery features including Cycle-by-Cycle current limiting, VDD over-voltage clamp and UVLO, and Power on soft start. Excellent EMI performance is achieved with On-Bright proprietary frequency shuffling technique together with soft switching control at the totem pole gate FEATURESPrimary-side Sensing and Regulation WithoutTL431 and Opto-couplerMulti-mode Operation for High Efficiency Programmable CV and CC RegulationFrequency Shuffling and Adjustable Gate Drive Greatly Improving EMIPower on Soft-start Time (4ms)“Extended Burst Mode Control” for Improved Efficiency and Minimum Standby Design Built-in Leading Edge Blanking Cycle-by-Cycle Current LimitingVDD Under Voltage Lockout with Hysteresis (UVLO)Gate Output Maximum Voltage Clamp (16V) Auto-restart in Short Circuit APPLICATIONSLow Power AC/DC offline SMPS for Cell Phone ChargerDigital Cameras Charger Small Power AdaptorAuxiliary Power for PC, TV etc. Linear Regulator/RCC Replacement OB2211 is offered in SOP8 package.OB2212 is offered in DIP8 packageTYPICAL APPLICATIONGENERAL INFORMATION Pin ConfigurationOB2211 is offered in SOP8OB2212 is offered in DIP8The pin map is shown as below.Ordering InformationPart Number DescriptionOB2211CP SOP8,Pb-freeOB2211CPA SOP8, Pb-free, T&ROB2212AP DIP8,Pb-freeNote: All Devices are offered in Pb-free Package if not otherwisenoted.Package Dissipation RatingPackage RθJA (°C/W)SOP8 150DIP8 90Absolute Maximum RatingsParameter ValueDrain Voltage (off state)-0.3V to 650VVDD Voltage -0.3 to 38 VVDDG Voltage -0.3 to 38 VVDD Zener Clamp ContinuousCurrent10 mACS Input Voltage-0.3 to 7VINV Input Voltage-0.3 to 7VMin/Max Operating JunctionTemperature T J-20 to 150 o CMin/Max Storage TemperatureT stg-55 to 150 oCLead Temperature (Soldering,10secs)260 oCNote: Stresses beyond those listed under “absolute maximumratings” may cause permanent damage to the device.

It operates in primary side sensing and regulation, thus opto-coupler and TL431 are not required. Proprietary CC control and built-in error amplifier can achieve a good CC/CV performance.z Startup Current and Start up ControlStartup current of OB2211/2 is designed to be very low so that VDD could be charged up above UVLO threshold level and device starts up quickly. A large value startup resistor can therefore be used to minimize the power loss yet reliable startup in application. For AC/DC adaptor with universal input range design, a 1.2 M Ω, 1/8 W startup resistor could be used together with a VDD capacitor to provide a fast startup and yet low power dissipation design solution.z Operating CurrentThe Operating current of OB2211/2 is as low as 1mA. Good efficiency is achieved with the low operating current together with ‘Extended burst mode’ control features.z Soft StartOB2211/2 features an internal 4ms soft start to soften the electrical stress occurring in the power supply during startup. It is activated during the power on sequence. As soon as VDD reaches UVLO(OFF), the peak current is gradually increased from nearly zero to the maximum clamping level 0.77V. Every restart is followed by a soft start.z CC/CV OperationOB2211/2 is designed to produce an approximate CV/CC output characteristic as shown in the figure 1. In charger applications, a discharged batteryoperates on the CC portion of the curve until almost fully charged and then smoothly switches to the CVportion of the curve. In an AC adapter, the normal operation occurs only on the CV portion of the curve, the CC portion provides over current protection and auto-restart short circuit protection. In CV operation, the output voltage is sensed on the primary side and the sensed signal controls the duty cycle through a built-in error amplifier (EA).Figure 1z Error Amplifier (EA)Connected to a resistor divider from the primary side sensing winding, the inverting input of the Error Amplifier (EA) is compared to an internal reference voltage of 1.25V to regulate the output voltage. The EA output is internally connected to the PWM generator and controls the duty cycle.z Primary Side Sensing and RegulationFigure 2 shows the simplified schematic of Flyback converter using primary side sensing and regulation. The voltage signal reflecting the output voltage from a feedback winding in the primary side is used to monitor and regulate the output voltage. The relationship of the DC voltage of the feedback winding and the output voltage is expressed as:()21F F o FB V V V N V −+⋅= (1)Where N is the turn ratio between the feedback winding and the output winding, V F1 is the forward drop voltage of the rectified diode, D1, and V F2is the forward drop voltage of the rectified diode, D2.FB INV V R R R V ⋅+=212(2)()()21212F F o V V V N R R R Vo −+⋅⋅+=(3)Figure 2In the regulation, V INV is regulated to 1.25V. V F1 of Diode D1 changes with the output current thus the load conditions, and V F2 is always constant regardless of output current, therefore, the regulation of output voltage, Vo, is affected by V F1 as shown in equation 3. To reduce the nonlinear effect of V F1, the N ratio needs is chosen to be small.z Loop CompensationTo provide good line and load regulation and dynamic response, a capacitor used for loop compensation is connected to pin INV as shown in Figure 3，where Req, Ceq and Roeq is respectively reflected effective ESR resistance, output capacitance and load resistance from the output winding to the primary side winding. The resistance Req and capacitance Ceq form a zero. The resistance Roeq and capacitance Ceq form a pole. The small signal transfer function of EA compensation circuit is obtained by:()1211221211C R R s C R s R R R A v v FBC +++⋅+⋅=ΛΛ(4)z Constant Current (CC) ModeTo achieve constant current (CC) at different output voltage, the Flyback converter is designed to operate in DCM mode and the switching frequency changes with output voltage as INV s V k f ⋅= and it is low clamped to12KHz, therefore the switching frequency is proportional to the output voltage as V INV is approximately the replica of output voltage, Vo .Figure 4 illustrates the key waveforms of the Flyback converter operating in discontinuous current mode (DCM). During Q1 on-time, theenergy can be stored in the primary inductor of the transformer; the load current is supplied from the output capacitor. The peak current of the primary side ramps up to I PK at the end of the on-time:on minpk T L V I ⋅=(5) In OB2211/2, the peak current at CC mode is always constant regardless of voltage level of V INV . The energy stored in the primary inductance Lm at the end of Ton is expressed by the current Ipk:()22pk m I L E ⋅=(6)where RsV I oc th pk _=, Rs is the current sensingresistor connecting to pin CS.During Q1 turns off, the energy stored in the primary winding is transferred to the secondary and output. The power drawn from the input AC supply is expressed by:()22pk s m I f L P ⋅⋅=(7)Assuming 100% efficiency, we can get the following equation at different output voltage,()o o pk s m I V I f L ×=⋅⋅⋅22(8)The output current is further expressed as()022V I f L I pk s m o ×⋅⋅⋅=(9)Since fs is linear proportional to Vo as described, therefore output current Io is kept constant and it depends only on L m and I pk .Fig. 4 The waveforms of Flyback converter in DCMz Extended Burst Mode OperationAt light load or zero load condition, most of the power dissipation in a switching mode power supply is from switching loss, the core loss of the transformer and the loss on the snubber circuit. The magnitude of power loss is in proportion to the switching frequency. Lower switching frequency leads to the reduction on the power loss and thus conserves the energy.OB2211/2 self adjusts the switching frequency according to the loading condition. The switch frequency is reduced at light/no load condition to improve the conversion efficiency. At light load/no load condition, the output of the Error amplifier (EA) drops below the burst mode threshold level and device enters Burst Mode control. The frequency control also eliminates the audio noise at any loading conditions.z Oscillator OperationThe switching frequency of OB2211/2 is internally fixed at 50KHZ. No external frequency setting components are required for PCB design simplification.z Frequency shuffling for EMI improvement The frequency Shuffling/jittering (switching frequency modulation) is implemented in OB2211/2. The oscillation frequency is modulated with a pseudo random source so that the tone energy is spread out. The spread spectrum minimizes the conduction band EMI and therefore eases the system design.z Current Sensing and Leading Edge BlankingCycle-by-Cycle current limiting is offered in OB2211/2 current mode PWM control. The switch current is detected by a sense resistor into the CS pin. An internal leading edge blanking circuit chops off the sensed voltage spike at initial internal power MOSFET on state due to snubber diode reverse recovery and surge gate current of internal power MOSFET so that the external RC filtering on sense input is no longer needed. The current limiting comparator is disabled and cannot turn off the internal power MOSFET during the blanking period. The PWM duty cycle is determined by the current sense input voltage and the EA output voltage.z DriveThe internal power MOSFET in OB2211/2 is driven by a dedicated gate driver for power switch control. Too weak the gate drive strength results in higher conduction and switch loss of MOSFET while too strong gate drive results the compromise of EMIA good tradeoff is achieved through the built-in totem pole gate design with right output strength and dead time control. The low idle loss and good EMI system design is easier to achieve with this dedicated control scheme.In addition to the gate drive control scheme mentioned, the gate drive strength can also be adjusted externally by a resistor connected between VDD and VDDG, the falling edge of the Drain output can be well controlled. It provides great flexibility for system EMI design.z Protection ControlGood power supply system reliability is achieved with its rich protection features including Cycle-by-Cycle current limiting (OCP), and VDD over voltage clamp, Power on Soft Start, Under Voltage Lockout on VDD (UVLO).With On-Bright Proprietary technology, the OCP is line voltage compensated to achieve constant output power limit over the universal input voltage range.VDD is supplied by transformer auxiliary winding output. It is clamped when VDD is higher than 30V. The output of OB2211 is shut down when VDD drops below UVLO(ON) limit and Switcher enters power on start-up sequence thereafter.PACKAGE MECHANICAL DATADimensions In Millimeters Dimensions In Inches SymbolMin Max Min MaxA 1.350 1.750 0.053 0.069A1 0.100 0.250 0.004 0.010 A2 1.300 1.550 0.051 0.061b 0.330 0.510 0.013 0.020c 0.170 0.250 0.006 0.010D 4.700 5.150 0.185 0.203E 3.800 4.000 0.150 0.157E1 5.800 6.200 0.228 0.244e 1.270 (BSC) 0.050 (BSC)L 0.400 1.270 0.016 0.050 θ 0º 8º 0º 8ºDimensions In Millimeters Dimensions In InchesSymbolMin Max Min MaxA 3.710 4.310 0.146 0.1700.500 0.020 A1A2 3.200 3.600 0.126 0.142B 0.350 0.650 0.014 0.026 B1 1.524 (BSC) 0.060 (BSC)C 0.200 0.360 0.008 0.014D 9.000 9.500 0.354 0.374E 6.200 6.600 0.244 0.260 E1 7.320 7.920 0.288 0.312e 2.540 (BSC) 0.100 (BSC)L 3.000 3.600 0.118 0.142 E2 8.200 9.000 0.323 0.354IMPORTANT NOTICERIGHT TO MAKE CHANGESOn-Bright Electronics Corp. reserves the right to make corrections, modifications, enhancements, improvements and other changes to its products and services at any time and to discontinue any product or service without notice.
