FAN6210 - Fairchild Semiconductor

FAN6210 Primary-Side Synchronous Rectifier (SR) Trigger Controller

FAN6210 is a primary-side trigger Integrated Circuit (IC) specially designed for the synchronous rectifier (SR) in dual forward converters employing FSR660/630. 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 converte.
