MP6925A - Synchronous Rectifier
MP6925A
Fast Turn-off, CCM/DCM Compatible Dual-LLC Synchronous Rectifier with improved Noise Immunity, and enhanced driver for fast switching
Description
The MP6925A 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 VFWD (about 45mV). The IC turns the MOSFETs off before the switching current goes negative.
The MP6925A has light-load functionality to latch off the gate driver under light-load conditions, thus limiting the current below 175μA.
The MP6925A’s fast turn-off enables both continuous conduction mode (CCM) and discontinuous conduction mode (DCM).
The MP6925A requires a minimal number of external components, and is available in an SOIC-8 package.
