Product Description

The MP6922 is a dual fast turn-off intelligent controller to drive two N-CH power MOSFETs in LLC resonant converters for synchronous rectification. The IC regulates the forward voltage drop of the power switch to about 70mV and turns it off before the voltage goes negative. MP6922 has a light-load function to latch-off the gate driver at light load condition, during which only about 600μA quiescent current is consumed. The fast turn-off speed of MP6922 makes both CCM and DCM driving available. An internal Reverse Current Protection (RCP) function ensures safe operation of the MOSFETs in high frequency CCM condition. MP6922 requires a minimum number of readily available standard external components and is available in SOIC8E, SOIC8 or SOIC14 package.
