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.
