High Efficiency Synchronous Rectification EV Board
The EV6923-S-00A is an evaluation board for the MP6923GS. It is configured to provide synchronous rectification solution for LLC topology.
MP6923 features dual synchronous gate outputs which enables high efficiency rectification by replacing the schottky rectifier with a low Ron MOSFET.

- Max 300kHz Switching Frequency
- <600μA Quiescent Current at Light Load Mode
- Supports CCM, CrCM and DCM Operation Mode
- Supports High-side and Low-side Rectification
- IC Supported 1MP6923
The MP6923 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 about 15mV. The IC turns off both MOSFETs before the switching current goes negative.
The MP6923 uses a light-load function to latch off the gate driver under light-load conditions, limiting the current to below 600μA.
The MP6923’s fast turn-off enables both continuous conduction mode (CCM) and discontinuous conduction mode (DCM). An internal anti-bounce logic function ensures safe MOSFET operation.
The MP6923 requires a minimal number of readily available, standard, external components and is available in a SOIC14 package.
