LOW COST POWER-SAVING MODE PWM CONTROLLER FOR FLYBACK CONVERTERS

The  UC3873B is a high performance current mode PWM controller ideally suited for low standby power. Low VDD startup current make the power reliable on startup design and a large value resistor could be used in the startup circuit to minimize the standby power. At no load condition, the IC operates UTC proprietary frequency hopping technology for Improved EMI performance. Power-saving mode for high light-load and standby efficiencySoft Start  Dynamic peak current limiting for constant output powerBuilt-in synchronized slope compensationOLP,OVP and VDD clamp for higher security-500/+500mA gate ;
