MP6922
Dual Fast Turn-off Intelligent Controller
The Future of Analog IC Technology
DESCRIPTION
FEATURES
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.
Works with both Standard and Logic Level
FETs
Compatible with Energy Star, 0.5W Standby
