The DiodesZetex APR340 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 APR340 can output ideal drive signal with less external components. The APR340 is available in the SOT26 package.
