DESCRIPTION

The MP6902 is a Low-Drop Diode Emulator IC

for Flyback converters which combined with an

external switch replaces Schottky rectification

diodes for high efficiency. The chip regulates

the forward drop of an external switch to about

70mV and switches it off as soon as the voltage

becomes negative. MP6902 has a light-load

sleep mode that reduces the quiescent current

to <300uA.

FEATURES

• Supports DCM and Quasi-Resonant

Flyback Converters

• Works with 12V Standard and 5V Logic

Level FETS

• Compatible with Energy Star, 1W Standby

Requirements

• Fast Turn-off Total Delay of 20ns

• Max 400kHz Switching Frequency

• <300μA Quiescent Current at Light Load

Mode

• 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
