FAN6208 Datasheet (Fairchild Semiconductor) - Secondary-Side Synchronous Rectifier Controller

FAN6208, Secondary-Side Synchronous Rectifier Controller

FAN6208 is a synchronous rectification (SR) controller for isolated LLC or LC resonant converters that can drive two individual SR MOSFETs emulating the behavior of rectifier diodes.

FAN6208 measures the SR conduction time of each switching cycle by monitoring the drain-to-source voltage of each SR
