DESCRIPTION

The MP6920 is a fast turn-off intelligent rectifier

for Flyback converters that combines a 60V

power switch that replaces diode rectifiers for

high efficiency. The chip regulates the forward

voltage drop of the internal power switch to

about 70mV and turns it off before the voltage

goes negative.

FEATURES

• Supports DCM and Quasi-Resonant

Flyback converters

• Integrated 10mΩ 60V Power Switch

• Compatible with Energy Star, 1W Standby

Requirements

• Max 300kHz Switching Frequency

• Supports High-Side and Low-Side

Rectification

• Power Savings of Up to 1.5W in a Typical

Notebook Adapter

APPLICATIONS

• Industrial Power Systems

• Distributed Power Systems

• Battery Powered Systems

• Flyback Converters
