The MP6923 is a dual, fast turn-off, intelligent rectifier for synchronous rectification in LLC resonant converters.
The IC drives two N-channel MOSFETs and regulates their forward voltage drop to about 15mV. The IC turns off both MOSFETs before the switching current goes negative.
The MP6923 uses a light-load function to latch off the gate driver under light-load conditions, limiting the current to below 600μA.
The MP6923’s fast turn-off enables both continuous conduction mode (CCM) and discontinuous conduction mode (DCM). An internal anti-bounce logic function ensures safe MOSFET operation.
The MP6923 requires a minimal number of readily available, standard, external components and is available in a SOIC14 package.
