MP6924, MP6924A Fast Turn-off, CCM/DCM Compatible Dual LLC Synchronous Rectifier with low Sleep Mode Current DESCRIPTION The MP6924, MP6924A 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 Vfwd(MP6924:45mV,MP6924A:29mV), and turns the MOSFETs off before the switching current goes negative. The MP6924, MP6924A has a light-load function to latch off the gate driver under lightload conditions, limiting the current to 175μA. The MP6924, MP6924A’s fast turn-off enables both continuous conduction mode (CCM) and discontinuous conduction mode (DCM).
