Concept常见问题
1．关于编程软件ConceptXS , ConceptS , ConceptM , ConceptXL主要区别。
ConceptXS和ConceptS 只能对Momentum PLC 进行编程, 无Concept Security。
ConceptM可对Compact 和Momentum PLC进行编程,无Concept Security。
ConceptXL可对Quantum、Compact、Momentum、Atrium进行编程，有Concept Security。
2．Concept S 和Concept M有多用户版吗？对于Concept软件而言, 只有XL版才有单用户和多用户版, 而Concept S 和Concept M 只有单用户版, 没有多用户版, 所以如果用户需要3个Concept M的拷贝的话, 那么用户必须定3套Concept M的单用户版.3. Quantum以太网模板140NOE771X0上Appl灯亮，是什么原因？怎样使之熄灭？NOE模板如果发生过系统崩溃，就会在模板内部创建一个记录文件，并且NOE模板上的Appl灯亮。
要想使之熄灭，用IE浏览器进入NOE模板，进入NOE Diagnostics，再进入Crash Log File Diagnostics，崩溃信息会显示出来，点击“Clear Crash Log File”，就可以清除这些崩溃信息，Appl灯也会熄灭。
4．在Concept2.2 SR2做I/O map时，找不到Quantum As-i模板140EIA92100，此模板有可能应用于Concept2.2 SR2下吗？Quantum As-i模板能配置在本地机架，RIO分站，DIO分站上吗？Concept2.2 SR2不支持As-i模板140EIA92100，必须是Concept v2.5，Modsoft v2.61，Proworx Nxt v2.1支持此模板。

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 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.
