FAN6248HDMX Advanced Synchronous Rectifier Controller for LLC Resonant Converter
The FAN6248HDMX, manufactured by onsemi, is a highly integrated, secondary-side synchronous rectifier (SR) controller specifically optimized for LLC resonant converter topologies. Designed to minimize external component count while maximizing power conversion efficiency, this IC features two independent gate driver stages to control synchronous rectification MOSFETs in the transformer's secondary winding. Operating over a wide frequency range of 25kHz to 700kHz and supply voltage up to 30V, it incorporates advanced adaptive control algorithms, including parasitic inductance compensation and light-load detection, ensuring stable and efficient performance across full load conditions. Engineered for high-density, high-efficiency power supply designs, it is ideal for modern AC-DC and DC-DC conversion systems demanding minimal power loss and reliable operation.
