The APR3401 is a secondary side MOSFET driver for synchronous rectification in DCM/QR/ACF 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 APR3401 can output ideal drive signal with less external components.
The APR3401 is available in the SOT26 package.
