Primary-Side Synchronous Rectifier (SR) Signal Trigger for Dual Forward ConverterGeneral DescriptionFAN6210 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 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. Product Status/Pricing/Packing
