MP6924GS Synchronous Rectifier

Monolithic Power Systems' MP6924 intelligent rectifier for synchronous rectification

Image of MPS's MP6924 Rectifier MPS' MP6924 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 about 45 mV, and turns the MOSFETs off before the switching current goes negative. The MP6924 has a light-load function to latch off the gate driver under light-load conditions, limiting the current to 175 μA. Its fast turn-off enables both continuous conduction mode (CCM) and discontinuous conduction mode (DCM). The MP6924 also requires a minimal number of readily available, standard, external components and is available in a SOIC-8 package.

Features
  • Works with 12 V standard and 5 V logic level MOSFETs
  • Compatible with Energy Star, 0.5 W standby requirements
  • Fast turn-off total delay of 35 ns
  • Wide 4.2 V ~ 35 V VDD operating range
  • 175 µA low quiescent current in light-load mode
  • Supports CCM, CrCM, and DCM operation
  • Supports high-side and low-side rectification
  • Power savings of up to 1.5 W in a typical notebook adapter
  • Available in a SOIC-8 package
Applications
  • AC/DC adapters
  • PC power supplies
  • LCD and LED TVs
  • Isolated DC/DC power converters
