LOW COST POWER-SAVING  MODE PWM CONTROLLER  FOR FLYBACK CONVERTERS

The  UC3873 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 i 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 securityProgramming OTP f;
