MP6922DN Datasheet | Monolithic Power Systems

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 70m V 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 ponents and is available in SOIC8E, SOIC8 or SOIC14 package. FEATURES - Works with both Standard and Logic Level FETs - patible with Energy Star, 0.5W Standby Requirements - VDD Range From 8V to 24V - 70m VDS Regulation Function (1) - Fast Turn-off Total Delay of 20ns - Reverse Current Protection Function - Max 300k Hz Switching Frequency - Light Load Mode Function (1) with <600u A Quiescent Current - Supports CCM, Cr CM and DCM Operation Mode - Available in SOIC8E, SOIC8 or SOIC14 package APPLICATIONS - AC-DC Adapter - LCD & PDP TV - Tele SMPS All MPS parts are lead-free and adhere to the Ro HS directive.
