LOW COST POWER-SAVING MODE PWM CONTROLLER FOR FLYBACK CONVERTERS

The UC3973 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 in • UTC proprietary frequency hopping technology for Improved EMI performance. \n• Power-saving mode for high light-load and standby efficiency \n• Soft Start   \n• Dynamic peak current limiting for constant output power \n• Built-in synchronized slope compensation \n• OLP,OVP and VDD clamp for higher;
