The final specification will be available once the complete circuitcharacterization has been :IM+Ics VBO4 Vcontrol*Vcontrol(min) PIN DESCRIPTIONSPinSym-bolNameFunction1 GNDG round 2 VinMultiplierVoltageThis pin provides a voltage VM for the PFC duty cycle modulation. The input impedance ofthe PFC circuits is proportional to the resistor RM externally connected to this pin. The deviceoperates in average current mode if an external capacitor CM is connected to the , it operates in peak current SenseInputThis pin sources a current ICS which is proportional to the inductor current IL. The sensecurrent ICS is for overcurrent protection (OCP), overpower limitation (OPL) and PFC dutycycle modulation.

7 When ICS goes above 200 mA, OCP is activated and the Drive Output Out / InConnect a resistor network among the rectified input voltage, BO pin, and ground. Andconnect a capacitor between BO pin and ground. BO pin detects a voltage signalproportional to the average input VBO goes below VBOL, the circuit that detects too low input voltage conditions(brown out), turns off the output driver and keeps it in low state until VBO exceeds signal which is proportional to the RMS input voltage Vac is also for overpower limitation(OPL) and PFC duty cycle Voltage/ Soft StartThe voltage of this pin Vcontrol directly controls the input impedance. This pin is connected toexternal type 2 compensation components to limit the Vcontrol bandwidth typically below 20Hz to achieve near unity Power device provides no output when Vcontrol < Vcontrol(min).

8 When it starts operation, thepower increases slowly (soft start).6 VFBFeed Back /ShutdownThis pin receives a feedback signal VFB that is proportional to the PFC circuits outputvoltage. This information is used for both the output regulation, the overvoltage protection(OVP), and output undervoltage protection (UVP) to protect the system from damage atfeedback abnormal VFB goes above 105% VREF, OVP is activated and the Drive Output is VFB goes below 8% VREF, the device enters a low consumption shutdown VoltageThis pin is the positive supply of the IC. The circuit typically starts to operate when VCCexceeds V and turns off when VCC goes below 9 V. After start up, the operating rangeis 9 V up to 20 OutputThe high current capability of the totem pole gate drive ( A) makes it suitable toeffectively drive high gate charge Power +-+105% Vref8% Vref with 4% VrefHysteresisUVPOVPU ndervoltageLock OutReferenceBlockBias BlockIrefVddVrefVccDRVGNDO utputBuffer871 UVL-OB-O+-OTA 28 mAVcontrolVrefOPLVddOff+-95% Vref65 QRSVdd+- current MirrorBO4 BOThermalShutdown+-Vref+-VmFigure 1.
