FAN6248HC Overview
Advanced Synchronous Rectifier Controller for LLC Resonant Converter FAN6248HC/HD/LC/LD The FAN6248 is an advanced synchronous rectifier (SR) controller that is optimized for LLC resonant converter topology with minimum external ponents. It has two driver stages for driving the SR MOSFETs which are rectifying the outputs of the secondary transformer windings. The two gate driver stages have their own sensing inputs...
