The MP6924 is a dual, fast turn-off, intelligent rectifier for synchronous rectification in LLC resonant converters. The IC drives two N-channel MOSFETs, regulates their forward voltage drop to about 45mV, and turns the MOSFETs off before the switching current goes negative.
The MP6924 has a light-load function to latch off the gate driver under light-load conditions, limiting the current to 175μA. The MP6924’s fast turn-off enables both continuous conduction mode (CCM) and discontinuous conduction mode (DCM).
The MP6924 requires a minimal number of readily available, standard external components, and is available in a SOIC-8 package.
