International Rectifier’s IR11672A SmartRectifier IC features advanced Minimum on Time (MOT) protection circuitry for energy-efficient AC/DC power converters for laptops, LCD and PDP televisions, game consoles, and server and telecom switch mode power supplies (SMPS). Utilizes IR’s proprietary 200V IC technology, the IR11672A is a smart secondary-side synchronous rectification (SR) controller designed to drive n-channel power MOSFETs used as synchronous rectifiers in isolated flyback and resonant half-bridge converters.
Other key features include maximum 500kHz switching frequency; 7A peak turn-off gate drive current; micropower start-up and ultra low quiescent current; 10.7V gate drive clamp; 50ns turn-off propagation delay; and 11.3V to 20V Vcc operating range.
