Dual Fast Turn-off Intelligent Rectifier, Vfwd 70mV for LLC
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.
High Efficient, Dual Fast Turn-off Intelligent Rectifier, Vfwd 30mV for LLC
The MP6922A is a dual, fast-turn–off, intelligent rectifier for synchronous rectification in LLC resonant converters. The IC drives two N-channel MOSFETs and regulates their forward voltage drop to about 30mV and turns it off before the switching current goes negative. MP6922A has a light-load function to latch off the gate driver under light-load conditions, thus limiting the current to below 600μA. The MP6922A’s fast turn-off enables both continuous-conduction mode and discontinuous-conduction mode. An internal reverse-current protection function ensures safe MOSFET operation under high-frequency continuous-current conditions. MP6922A requires a minimal number of readily-available standard external components and is available in SOIC8E, SOIC8, and SOIC14 packages.
