APR346
SECONDARY SIDE SYNCHRONOUS RECTIFICATION CONTROLLER Description Pin Assignments The APR346 is a secondary side MOSFET driver for synchronous
rectification, supports CCM, DCM and Quasi-Resonant Flyback
Topologies. (Top View) NEW PRODUCT 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, the APR346
can output ideal drive signal with less external components. It can
provide high performance solution for 5V to 20V output voltage
application.
The APR346 is available in SOT26 package. AREF 1 6 DRISR GND 2 5 CCM VDET 3 4 VCC Features
