MP6922 Dual Fast Turn-off Intelligent Controller The Future of Analog IC Technology DESCRIPTION FEATURES The MP6922 is a dual fast turn-off intelligent Works with both Standard and Logic Level controller to drive two N-CH power MOSFETs FETs in LLC resonant converters for synchronous Compatible with Energy Star, 0.5W Standby rectification. Requirements V Range From 8V to 24V DD The IC regulates the forward voltage drop of the (1) 70m VDS Regulation Function power switch to about 70mV and turns it off Fast Turn-off Total Delay of 20ns before the voltage goes negative. Reverse Current Protection Function MP6922 has a light-load function to latch-off the Max 300kHz Switching Frequency gate driver at light load condition, during which (1) Light Load Mode Function with <600uA only about 600A quiescent current is Quiescent Current consumed. Supports CCM, CrCM and DCM Operation The fast turn-off speed of MP6922 makes both Mode CCM and DCM driving available. An internal Available in SOIC8E, SOIC8 or SOIC14 Reverse Current Protection (RCP) function package ensures safe operation of the MOSFETs in high APPLICATIONS frequency CCM condition. AC-DC Adapter MP6922 requires a minimum number of readily LCD & PDP TV available standard external components and is Telecom SMPS available in SOIC8E, SOIC8 or SOIC14 All MPS parts are lead-free and adhere to the RoHS directive.
