MP6922A

The MP6922A 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 30mV and turns it off before the switching current goes negative. MP6922A has a light-load function to latch off the gate driver under light-load conditions, thus limiting the current to below 600μA. The MP6922A’s fast turn-off enables both continuous-conduction mode and discontinuous-conduction mode. An internal reverse-current protection function ensures safe MOSFET operation under high-frequency continuous-current conditions. MP6922A requires a minimal number of readily-available standard external components and is available in SOIC8E, SOIC8, and SOIC14 packages.
