High Efficiency Synchronous Rectification Evaluation Board
The EV6925-S-00A from Monolithic Power Systems, Inc. is an evaluation board for the company's MP6925GS integrated circuit. It is configured to provide synchronous rectification solution for LLC topology.
MP6925GS features dual synchronous gate outputs which enables high efficiency rectification by replacing the Schottky rectifier with a low Ron MOSFET.
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.
