Product Descriptions
The MP6902 is a Low-Drop Diode Emulator IC for Flyback converters which combined with an external switch replaces Schottky rectification diodes for high efficiency. The chip regulates the forward drop of an external switch to about 70mV and switches it off as soon as the voltage becomes negative. MP6902 has a light-load sleep mode that reduces the quiescent current to <300uA.
