UC3838 友顺UTC 电子元器件芯片

UNISONIC TECHNOLOGIES CO., LTDUC3838Preliminary CMOS IC LOW COST POWER-SAVINGMODE PWM CONTROLLERFOR FLYBACK CONVERTERSDESCRIPTIONThe UTC UC3838provides a CCM switching mixed modeoperation for better efficiency performance. The operation modestays at CCM at heavy load, and switch to power-saving mode atlight load.The UTC UC3838is a high performance current mode PWMcontroller ideally suited for low standby power. Low V CC startupcurrent make the power reliable on startup design and a largevalue resistor could be used in the startup circuit to minimize thestandby power. At no load condition, the IC operates inpower-saving mode for lower standby power, decreasing frequencyfor Higher conversion efficiency at light load condition.The UTC UC3838contains protection with automatic recoveryincluding OLP (over load protection), OCP (cycle-by-cycle currentlimiting), and UVLO (V CC over voltage clamp and under voltagelockout). It also provides the protections including OTP (overtemperature protection), OVP (V CC or DC output over voltageprotection) with automatic recovery. To protect the powerMOSFET, Gate-drive output is fixed up to 17V max.The internal slope compensation improves system stability athigh PWM duty cycle output. Leading-edge blanking on currentsense input removes the signal glitch, which offering minimaexternal component count in the design. Excellent EMIperformance is achieved with UTC propriet ary frequency hoppingtechnique together with soft driver control. Audio noise iseliminated due to switch frequency more than 20kHz duringoperation.UTC UC3838 is packaged by using tiny SOT-26 package. It hassuch applications as: battery charger, power adaptor, set-top boxpower supplies, ink jet printers, open-frame SMPS.FEATURES*Proprietary frequency hopping for Improved EMI performance*Cycle-by-cycle current limiting*CCM Power-saving mode Switching Operation*Fixed switch frequency 65kHz TYP.*Dynamic peak current limiting for constant output power*Built-in synchronized slope compensation*Gate output voltage clamped at 17V*Adjustable DC output OVP/OTP*OLP/V CC OVP/Internal OTP (automatic recovery)*Internal Soft Start*OTP through a NTC (latch mode)ORDERING INFORMATIONMARKINGPIN CONFIGURATIONPIN DESCRIPTIONBLOCK DIAGRAMABSOLUTE MAXIMUM RATINGAbsolute maximum ratings are stress ratings only and functional device operation is not implied. RECOMMENDED OPERATING CONDITIONSTHERMAL DATAELECTRICAL CHARACTERISTICS (V CC=15V, T A=25°C, unless otherwise specified)ELECTRICAL CHARACTERISTICS (Cont.)APPLICATION NOTEThe UTC UC3838 devices integrate many useful designs into one controller for low-power switch-mode power supplies. The following descriptions highlight some of the features of the UTC UC3838 series. Start-up CurrentThe start-up current is only 1μA. Low start-up current allows a start-up resistor with a high resistance and a low-wattage to supply the start-up power for the controller. For AC/DC adaptor with universal input range design, a 2.5~3MΩ, startup resistor could be used together with a V CC capacitor to provide a fast startup and low powerdissipation solution. The D1 IN4148 can improve surge capability to 6.6KV.Fig. 1 Startup CircuitOperation ModeThe UTC UC3838 provides a CCM switching mixed mode operation for better efficiency performance. The operation mode stays at CCM at heavy load, once if the converter enters into DCM, the UTC UC3838automaticallyfinds the local minimum VDSpoint and switching at this local.Normally, the conduction loss is dominated at heavy load condition, and the switching loss turns to be larger than conduction loss in light load, especially at 1/4 ~ 1/2 of full load. By this kind of mixed mode operation to have CCM inheavy load and switching in light load can optimize the overall average efficiency during the entire operation range.APPLICATION NOTE (Cont.)As shown in Fig. 3, at deep light-load or no-load condition, the switching loss is the dominant factor. To improve the light-load efficiency, burst mode operation will stop the switching cycle of the OUT pin when FB pin voltage is below “V FB_IN” Level and restart the switching cycle of the OUT pin when FB pin voltage is above “V FB_OUT”.Over Voltage Protection on V CC Pin ( V CC OVP )The V CC OVP will shut down the switching of the power MOSFET whenever V CC>V OVP. The OVP event as followed Fig.4.Fig.4 OVP case Fig.5 OLP caseOver Load &Open Loop & Output Short Protection ( OLP or OSP )OLP or OSP will shut down driver when V FB> V OLP for continual a blanking time. The OLP or OSP event as followed Fig.5.Over Temperature Protection ( OTP )OTP will shut down driver when the NTC resistor temperature T J>T (THR).Pull this pin below 0.95V to shutdown the controller into latch mode until AC power-on againAPPLICATION NOTE (Cont.)Adjustable OTP & OVP Protection on OTP PINThe OTP circuit is implemented to sense whether there is any hot-spot of power circuit like power MOSFET or output rectifier. Once an over-temperature condition is detected, the OTP is enabled to shut down the controller to protect the controller. Typically, a NTC is recommended to connect with OTP pin. The NTC resistance will decrease as the device or ambient in high temperature. The relationship is as below.NTCOTP R ×A μ100=V When the V OTP is below the defined voltage threshold (typ. 0.95V), UTC UC3838 will shutdown the gate output and latch off the power supply. There are 2 conditions required to restart it successfully. First, cool down the circuit so that NTC resistance will increase and raise V OTP up above 1.05V. Then, VCC recovery, until AC power-on again An over voltage protection for OTP pin is fulfilled by monitoring the voltage V CC1 after the zener connected in series to the VCC. When V CC1 exceeds V OTP_OVP (typ. 4.28V), output will shutdown until AC power-on again.Z+OVP _OTP )OVP (CC V V =VFig. 6 OTP-Pin ProtectionAPPLICATION NOTE (Cont.)Cycle by Cycle Over-Current Protection (OCP)In a Flyback topology converter, the main MOSFET switch of the Flyback converter turns on and off rapidly. The energy is stored in the inductor when the MOSFET turns on. The inductor current flowing through the sensing resistor (R CS ) is shown in Fig.7. The current limit is determined by the equation below:CSCS MAX _PEAK R V =I In order to prevent the CS pin from false triggering, an internal leading edge blanking time (350nS Typ.) is added and an external low pass RC filter is also recommended to filter the turn-on spike of CS node.In general, the power converter can deliver more current at high input voltage than at low input voltage. To compensate this, an offset voltage is added to the CS signal by an internal current source (I OCP ) and an external resistor (R OCP ) in series between the sense resistor (Rcs) and the CS pin, as shown in Fig.8. By selecting a proper value of the resistor in series with the CS pin, the amount of compensation can be adjusted. The value of I OCP depends on the duty cycle of OUT pin. The relation curve between I OCP and duty is shown in Figure 7.Fig. 7 Current SensingFig. 8 AC input Compensation ON CS-PINAPPLICATION NOTE (Cont.)In light load conditions, the offset should be removed since it is in same order of magnitude as the current sense signal. Therefore the compensation current is only fully added when the FB voltage is higher than 2.27V. R OCP: 470~1.2k, C OCP: 47pF~390pF.An output overvoltage protection is implemented in the UTC UC3838, as shown in Fig. 9. It senses the auxiliary voltage via the divided resistors. The auxiliary winding voltage is reflected from secondary winding and therefore the flat voltage on the CS pin is proportional to the output voltage. UTC UC3838 can sample this flat voltage level after a delay time to perform output over voltage protection. This delay time is used to ignore the voltage ringing from leakage inductance of PWM transformer. The sampling voltage level is compared with internal threshold voltage 0.2V. If the sampling voltage exceeds the OVP trip level, an internal counter starts counting subsequent OVP events. The counter has been added to prevent incorrect OVP detection which might occur during ESD or lightning events. However, when typically 7 cycles of subsequent OVP events are detected, the OVP circuit switches the power MOSFET off. As the protection is occur, the converter only restarts after VCC auto-recovery.(a)Out(b)Fig. 9 DCOVP ON CS-PINAPPLICATION NOTE (Cont.)MOSFET CharacteristicThe MOSFET is divided into three operation regions, ohmic region, saturation region, and the cut-off region, shown as Fig. 10(a). For switching power supply applications, it shall operate in ohmic and cut-off region. Never reach the region of saturation; it would cause damage for acting beyond the maximum safety operating area. It’s necessary to check the characteristic of MOSFET. Fig.10(c) shows a totem pole architecture for the circuit of OUT. The output high level of OUT is at around V CC-1.5V. Refer to on-region characteristics of the MOSFET, check the saturation current of V GS H(MIN) to make sure the saturation current is high enough to activate MOSFET to operate in ohmic region. In order not to decrease the voltage across V G, it’s recommended not to connect a forward diode between the gate of the MOSFET and OUT pin, for example like Fig.10(d) . In addition, pulling V CC level high can keep V GSH in high level, for example:(1). Increase NX value to pull V CC level high. (2). Increase V CC capacitance to improve V CC’s performance to drop at startup transient, shown as Fig.10(b) .(a)(b)RS(c) (d)Fig.10 MOSFET CharacteristicTYPICAL APPLICATION CIRCUIT。

UTC386中文资料下载

UTC386 双极型线性集成电路资料版权: 第一价值网(IC网络超市) 低电压音频功率放大器概述:UTC386音频功率放大器主要应用于低电压消费类产品。

为使外围元件最少，电压增益内置为20。

但是在1脚和8脚之间增加一只外接的电阻和电容，便可将电压增益调为任意值，直至200。

输入端以地为参考，同时输出端被自动偏置到电源电压的一半。

在6V电源电压下，它的静态功耗仅为24mW，使得UTC386特别适合于电池供电的场合。

特点:1.静态功耗低，约为4mA,可用电池供电2.工作电压范围宽，5-18V3.外围元件少4.电压增益由20—200可调5.失真度低应用范围1.AM/FM收音机音频放大器2.线驱动器3.便携式录音机音频功率放大器4.超声波驱动器5.免提电话机扬声系统6.小型伺服驱动器7.电视机音频系统8.电源变换器内部等效电路管脚排列图极限参数(TA=25℃)注：在高于25℃的环境中工作时，由于最高结温为150℃，输出能力必须下降。

结到空气的热阻为80℃/W . 应用要点增益控制为了使UTC386应用起来更灵活些，提供了两条增益控制管脚(1脚和8架)。

当1脚和8脚开路时，1.35KΩ的电阻将增益置为20(26dB)；当1脚和8脚外接一只电容将1.35 KΩ电阻旁路时，增益上升到200(46dB)。

如果外接一只电阻和电容串联，增益将在20 至200之间可任意调节。

增益的控制也可通过在1脚和地之间交流耦合一只4电阻(FET) 来实现。

在一些特殊的应用中，也可平行于内部负反馈电阻外接阻容元件来进行增益和频响调整。

例如，我们可以通过提升负反馈频响网络以补偿扬声器低频段灵敏度低的缺点，它可以通过在1脚和5脚之间(平行于内部15KΩ电阻)接一个RC串联网络来实现。

对于6dB的有效低频提升来说：R≈15KΩ，当8脚开路时，能保证稳定工作的R最小值为R=10KΩ，如果1脚和8脚之间有旁路电容，则R的最小值降为R=2KΩ，有这项限制的原因为放大器内部补偿仅至闭环增益大于9。

环输增入益大偏于置9。
从内部等效电路可以看到，两个输入端各有一只50KΩ的电阻接到地，输入晶体管的基极电流约为250nA，所以输入端在开路时约有12.5mV的电压。当驱动UTC386直流信号源的内阻大于250KΩ时，它将产生很小的附加失调(输入端约为2.5mV，输出端约为50mV)。当直流信号源的内阻小于10KΩ时，将不用的那个输入端接地，也可以做到很小的附加失调(输入端约为2.5mV，输出端约为50mV)。当直流信号源的内阻在上述两者之间时，我们可以通过在不用的那个输入端与地之间接一只与信号源内阻一样大的电阻来消除附加失调。当然，输入端用交流耦合时,上面提到的附加失调电压问题就不存在了。
