FAN6248 Advanced Synchronous Rectifier Controller

Pin Number Pin Name 1 GATE1 2 GND 3 VD1 4 VS1 5 VS2 6 VD2 7 VDD 8 GATE2 Description Gate drive output for SR1 Ground Synchronous rectifier drain sense input. A IOFFSET1 current source flows out of the DRAIN pin such that an external series resistor can be used to adjust the synchronous rectifier tu.

FAN6248HC/HD/LC/LD Advanced Synchronous Rectifier Controller for LLC Resonant Converter The FAN6248 is an advanced synchronous rectifier (SR) controller that is optimized for LLC resonant converter topology with minimum external components. It has two driver stages for driving the SR MOSFETs which are rectifying the outputs of the secondary transformer windings. The two gate driver stages have their own sensing inputs and operate independently of each other. The adaptive parasitic inductance co.
