LOW COST POWER-SAVING MODE PWM CONTROLLER FOR FLYBACK CONVERTERS

The UTC UC3875L is a high performance current mode PWM controller ideally suited for low standby power. The PWM switching frequency is programmable externally at normal operation. Low VDD startup current make the power reliable on startup design and a large value resistor could be? used in the start UTC proprietary frequency hopping technology for Improved EMI performance.?Lower than 30mW Standby Power DesignDynamic peak current limiting for constant output powerBuilt-in synchronized slope compensationOLP with automatic recoveryOTP and OVP with latch upVDD clamp for higher securityProgrammable ;
