Description
FAN6210 is a primary-side SR trigger Integrated Circuit
(IC) specially designed for the synchronous rectifier
(SR) in dual forward converters employing FAN6206.
FAN6210 provides drive signal for the primary-side
power switches by using an output signal from PWM
controller. FAN6210 can be combined with any PWM
controller that can drive a dual-forward converter. To
obtain optimal timing for the SR drive signals,
transformer winding voltage is also monitored. To
improve light-load efficiency, green mode operation is
employed, which disables the SR turn-on trigger signal,
minimizing gate drive power consumption at light load.
FAN6210 is available in 8-pin SOP package.
