FAN6248 Product details

Description

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 turn-off threshold.The IOFFSET1 current source is turned off when VDD is under-voltage or when switching is disabled in green mode Synchronous rectifier source sense input for SR1 Synchronous rectifier

Features

Highly Integrated Self-contained Control of Synchronous Rectifier with a Minimum External Component Count.
Optimized for LLC Resonant Converter.
Anti Shoot-through Control for Reliable SR Operation.
Separate 100 V Rated Sense Inputs for Sensing the Drain and Source Voltage of each SR MOSFET.
Adaptive Parasitic Inductance Compensation to Minimize the Body Diode Conduction.
SR Current Inversion Detection under Light Load Condition.
Li.
