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.
