MP6925A - Synchronous Rectifier

General 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.

Key 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.

MP6925A Fast Turn-Off, CCM/DCM Compatible, Dual-LLC, Synchronous Rectifier with lmproved Noise Immunity 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.
