MP6922
Dual Fast Turn-off Intelligent Controller
The Future of Analog IC Technology
DESCRIPTION
The MP6922 is a dual fast turn-of f intelligent
controller to drive two N-CH powe r 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 of f
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 600 μA quiescent current is
consumed.
The fast tur n-off speed of MP6922 makes both
CCM and DCM drivin g available. An internal
Reverse Current Protection (RCP) function
ensures safe operation of the MOSFETs in hig h
frequency CCM condition.
MP6922 requires a minimum nu mber of readily
available st andard external components and is
available in SOIC8E, SOIC8 or SOIC14
package.
