Monolithic Power Systems (MPS) MP6973 CCM/DCM Flyback Ideal Diodes

Monolithic Power Systems (MPS) MP6973 CCM/DCM Flyback Ideal Diodes are fast turn-off, intelligent rectifiers for flyback converters integrating a 100V/14mΩ MOSFET. The MP6973 is ideal for replacing a diode rectifier achieving 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 MPS MP6973 CCM/DCM Flyback Ideal Diodes are optimized for low-side rectification. Furthermore, internal ringing detection circuitry prevents the device from falsely turning on during discontinuous conduction mode (DCM) or quasi-resonant operations.

The MP6973 features a wide output range down to 0V and is housed in a SOIC-8 package.
