APR345K6TR-G1

NOT RECOMMENDED FOR NEW DESIGN USE APR348 APR345 SECONDARY SIDE SYNCHRONOUS RECTIFICATION CONTROLLER Description Pin Assignments The DIODES™ APR345 is a secondary side MOSFET driver for synchronous rectification, supports CCM, DCM and Quasi-Resonant Flyback Topologies. (Top View) Pin 1 Mark 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. AREF 1 6 DRISR GND 2 5 CCM VDET 3 4 VCC The APR345 is available in SOT26 package.
