CCM/DCM Flyback Ideal Diode with Integrated 100V/14mΩ MOSFET with Slew Rate Detection

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 t
