AP3902 - LOW POWER PWM SWITCH

Datasheet Summary

Description

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.

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. AP3902 Features.

Data Sheet LOW POWER PWM SWITCH FOR OFF-LINE SMPS General Description 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 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.
