LOW POWER PWM SWITCH FOR OFF-LINE SMPS

AP3902

BCD Semiconductor Manufacturing Limited

Sep. 2008 Rev. 1.0

General Description

The AP3902 PWM power switch consists of a fixed-

frequency current-mode PWM controller and a high

voltage transistor. It is specifically designed for high

performance off-line switching power supplies or non-

isolated small household applications. Compared to

discrete MOSFET and PWM controller power supply

solutions, AP3902 solution offers advantages such as

fewer component numbers, smaller size, and lower

total cost.

In normal operation, the 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 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.
