Product Description

The MP6905 is a low-drop, diode-emulator IC with external switch; MP6905 replaces Schottky diodes in high-efficiency, flyback converters. The chip regulates the forward drop of the external switch (about 30mV) and switches it off when the voltage becomes negative. MP6905 has a light-load sleep mode that reduces the quiescent current to <300uA. MP6905 is available in a compact SOIC-8 package.

Kit details

The EV6905-S-00A is an evaluation board for the MP6905GS. It is configured to provide synchronous rectification solution for Flyback/LLC topology.

MP6905GS features a synchronous gate output which enables high efficiency rectification by relating the schottky rectifier with a low Ron MOSFET.
