Description

The APR34709 is a secondary side Combo IC, which combines an N-Channel MOSFET and a driver circuit designed for Synchronous Rectification (SR), supports DCM and Quasi-Resonant Flyback Topologies.

The N-Channel MOSFET is 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, the APR34709 can output ideal drive signal with less external components.

It can provide high performance solution for 3.3V to 15V output voltage application.

The APR34709 is available in SO-8EP package.

Feature(s)

• Synchronous Rectification for DCM Operation Flyback
• Eliminate Resonant Ring Interference
• Fast Detector of Supply Voltages
• Fewest External Components

Application(s)

• Adapters/Chargers for Cell/Cordless Phones, ADSL Modems, MP3 and Other Portable Apparatus
• Standby and Auxiliary Power Supplies
