LOW COST POWER-SAVING MODE PWM CONTROLLER FOR FLYBACK CONVERTERS

The UTC UC3873C is a high performance current mode PWMcontroller ideally suited for low standby power. Low VDD 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 i UTC proprietary frequency hopping technology for Improved EMI performance. Power-saving mode for high light-load and standby efficiency Soft Start Dynamic peak current limiting for constant output power Built-in synchronized slope compensation OLP with automatic recovery OTP and OVP( automatic recov;
