APR345 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, APR345 can output ideal drive signal with less external components. It can provide high performance solution for 5V to 12V output voltage application.
The APR345 is available in SOT26 package.
