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

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 which is controlled by the internal protection unit. This IC adopts frequency dithering technique to reduce EMI. The AP3902 is available in DIP-8 package. AP3902 Features.
