DESCRIPTION

The MP6973 is a fast turn-off, intelligent rectifier

for

flyback

converters

that

integrates

a

100V

/14mΩ MOSFET. It can replace a diode

rectifier for higher efficiency and power density.

The chip regulates the forward voltage drop of

the internal power switch to VFWD (40mV) and

turns

off

before

the

drain-source

voltage

reverses.

The

MP6973

is

optimized

for

low-side

rectification.

The

internal

ringing

detection

circuitry prevents the MP6973 from falsely

turning on during discontinuous conduction

mode (DCM) or quasi-resonant operations.

The MP6973 is available in an SOIC-8 package.

FEATURES

 Integrated 100V/14mΩ MOSFET

during DCM Operations

 Compatible with Energy Star

 110µA Quiescent Current

 Supports DCM, CCM, and Quasi-Resonant

Operations

 Wide Output Range Down to 0V

 Available in an SOIC-8 Package

APPLICATIONS

 Laptop Adapters

 QC and USB PD Chargers

 High-Efficiency Flyback Converters
