UC3873C Datasheet (UTC) - LOW COST POWER-SAVING MODE PWM CONTROLLER

UC3873C, LOW COST POWER-SAVING MODE PWM CONTROLLER

The UTC UC3873C 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 operat
