2012-12-06 Fast turn off, Intelligent Synchronous Rectifier with Vfwd=30Mv for flyback converters
The ART6905 is a low-drop, diode-emulator IC with external switch; ART6905 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. ART6905 has a light-load sleep mode that reduces the quiescent current to <300uA. ART6905 is available in a compact SOIC-8 package.
