MP6925 - Dual-LLC Synchronous Rectifier

Description

The MP6925 is a dual, fast turn-off, intelligent rectifier for synchronous rectification in LLC resonant converters.

The IC drives two N-channel MOSFETs, regulates their forward voltage drop to Vfwd (about 29mV), and turns the MOSFETs off before the switching current goes negative.

Features

  • Works with Standard and Logic Level MOSFETs.
  • Compatible with Energy Star.
  • Fast Turn-Off Total Delay of 35ns.
  • Wide 4.2V to 35V VDD Operating Range.
  • 175µA Low Quiescent Current in Light-Load Mode.
  • Supports CCM, CrCM, and DCM Operation.
  • Supports High-Side and Low-Side Rectification.
  • Available in an SOIC-8 Package.

MP6925 Fast Turn-Off, CCM/DCM Compatible, Dual-LLC Synchronous Rectifier with lmproved Noise Immunity DESCRIPTION The MP6925 is a dual, fast turn-off, intelligent rectifier for synchronous rectification in LLC resonant converters. The IC drives two N-channel MOSFETs, regulates their forward voltage drop to Vfwd (about 29mV), and turns the MOSFETs off before the switching current goes negative. The MP6925 has a light-load function to latch off the gate driver under light-load conditions, limiting the current to 175μA. The MP6925’s fast turn-off enables both continuous conduction mode (CCM) and discontinuous conduction mode (DCM). The MP6925 requires a minimal number of external components, and is available in an SOIC-8 package.
