i MP6900 J Fast Turn-off Intelligent Rectifier The Future of Analog IC Technology., DESCRIPTION The MP6900 is a low-drop, fast turn-off intelligent rectifier that combined with an external switch replaces Schottky diodes in high-efficiency, Flyback converters. The chip regulates the forward drop of an external switch to about 70mV and switches it off as soon as the voltage becomes negative. Package choices are a space saving TSOT23-5, QFN6 (3x3mm) or SOIC-8. FEATURES  Works with both Standard and Logic Level FETS Օ Compatible with Energy Star, 1W Standby Requirements  VDD Range From 8V to 24V Օ Fast Turn-off Total Delay of 20ns  Max 400kHz Switching Frequency Օ <3mA Low Quiescent Current  Supports CCM, DCM and Quasi-Resonant Topologies Օ Supports High-side and Low-side Rectification  Power Savings of Up to 1.5W in a Typical Notebook Adapter APPLICATIONS Օ Industrial Power Systems  Distributed Power Systems Օ Battery Powered Systems  Flyback Converters For MPS green status, please visit MPS website under Quality Assurance.
