APR347
APR347 is SECONDARY SIDE SYNCHRONOUS RECTIFICATION CONTROLLER manufactured by Diodes Incorporated.
NEW PRODUCT
SECONDARY SIDE SYNCHRONOUS RECTIFICATION CONTROLLER
Description
The APR347 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 APR347 can output ideal drive signal with less external ponents. It can provide high performance solution for 3.3V to 15V output voltage application.
The APR347 is available in SOT26 package.
