MP6902 Fast Turn-off Intelligent Controller The Future of Analog IC Technology DESCRIPTION FEATURES The MP6902 is a Low-Drop Diode Emulator IC Supports DCM and Quasi-Resonant for Flyback converters which combined with an Flyback Converters external switch replaces Schottky rectification Works with 12V Standard and 5V Logic diodes for high efficiency. The chip regulates Level FETS the forward drop of an external switch to about Compatible with Energy Star, 1W Standby 70mV and switches it off as soon as the voltage Requirements becomes negative. MP6902 has a light-load V Range From 8V to 24V DD (1) sleep mode that reduces the quiescent current 70mV V Regulation Function DS to <300uA. Fast Turn-off Total Delay of 20ns Max 400kHz Switching Frequency (1) Light Load Mode Function with <300 A Quiescent Current Supports High-side and Low-side Rectification Power Savings of Up to 1.5W in a Typical Notebook Adapter APPLICATIONS Industrial Power Systems Distributed Power Systems Battery Powered Systems Flyback Converters All MPS parts are lead-free and adhere to the RoHS directive.
