Description

APR34150 is a secondary side Combo IC, which combines an N-Channel MOSFET and a driver circuit designed for synchronous rectification (SR) in DCM operation.

The N-Channel MOSFET has been optimized for low gate charge, low RDS(ON), fast switching speed and body diode reverse recovery performance.

The synchronous rectification can effectively reduce the secondary side rectifier power dissipation and provide high performance solution. By sensing MOSFET drain-to-source voltage, APR34150 can output ideal drive signal with less external components. It can provide high performance solution for 5V output voltage application.

The APR34150 is available in SO-8 package.
