FAN6248
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.
Key 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
- Light Load Detection to Increase Dead Time Target
- Adaptive Minimum on Time for Noise Immunity
- Operating Voltage Range up to 30 V
- Low Start-up and Stand-by Current Consumption
