MP6902
Fast Turn-off Intelligent Controller
The Future of Analog IC Technology
DESCRIPTION
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.
