APR347 SECONDARY SIDE SYNCHRONOUS RECTIFICATION CONTROLLER

APR347 SECONDARY SIDE SYNCHRONOUS RECTIFICATION CONTROLLER

The APR347 is a secondary side MOSFET driver for synchronous rectification in DCM operation. 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 APR347 can out.
