UC3837 - LOW COST POWER-SAVING MODE PWM CONTROLLER

The UC3837 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.
