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 and determines
the optimal timing of the SR gate drive. FAN6208 uses
the change of opto-coupler diode current to adaptively
shrink the duration of SR gate drive signals during load
transients to prevent shoot-through. To improve light-
load efficiency, Green-Mode operation is employed,
which disables the SR drive signals, minimizing gate
drive power consumption at light-load condition.
Optimal timing circuits and protection functions are
integrated in an 8-pin SOP package, which allows high-
efficiency power supply design with fewer components.
