UC3849B Datasheet - UTC

UC3849B LOW COST POWER-SAVING MODE PWM CONTROLLER

The UC3849B 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 .
