MP6928A - Dual-Channel Intelligent Rectifier

Features

  • The MP6928A is a dual-channel, 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 adaptive VFWD. The IC turns the MOSFETs off before the switching current goes negative. The MP6928A has light-load functionality to latch off the gate driver under light-load conditions, thus limiting the current below 150μA. Fast turn-off enables continuous conduction mode and discontinuous.
