MP6922A
Dual, Fast-Turn–Off, Intelligent Rectifier
The Future of Analog IC Technology
DESCRIPTION
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.
