AP3902 Datasheet (BCD) - LOW POWER PWM SWITCH

AP3902, LOW POWER PWM SWITCH

The AP3902 PWM power switch consists of a fixedfrequency current-mode PWM controller and a high voltage transistor.

It is specifically designed for high performance off-line switching power supplies or nonisolated small household applications.

Compared to discrete MOSFET and PWM controller power sup

AP3902 Features

* with a fixed switching frequency. When the output power falls below a given level, the circuits automatically switches to a burst mode by skipping some switching cycles. In case of failure modes like open loop, over voltage or overload due to short circuit, the device switches into auto restart mode
