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
