APR346 Datasheet SECONDARY SIDE SYNCHRONOUS RECTIFICATION CONTROLLER

Manufacturer: Diodes Incorporated

General Description

The APR346 is a secondary side MOSFET driver for synchronous rectification, supports CCM, DCM and Quasi-Resonant Flyback Topologies.

The synchronous rectification can effectively reduce the secondary side rectifier power dissipation and provide high performance solution.

By sensing primary MOSFET gate-to-source voltage, the APR346 can output ideal drive signal with less external components.
