Description

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 output ideal drive signal with less external components. It can provide high performance solution for 3.3V to 15V output voltage application.

The APR347 is available in SOT26 package.
