High-efficiency rectification, board-level conversion and protected fan-power solutions for dense AI servers, accelerator platforms and high-performance data-center infrastructure.
High-density power delivery for AI accelerators, processors and server cooling systems
AI servers demand tightly coordinated power conversion from the rack or server power supply to high-current motherboard rails. The architecture combines fast-recovery rectification around the isolated conversion stage, low-voltage synchronous rectifier MOSFETs for efficient secondary conversion, medium-voltage step-down MOSFETs for board-level intermediate rails, and protected fan-supply load switches for high-availability cooling. Together these functions help reduce conduction and switching losses, improve transient response and maintain reliable operation under rapidly changing GPU, CPU and accelerator workloads.

About the solution
Efficient power conversion from the isolated server supply to high-current accelerator rails
AI server power systems must transfer large amounts of energy while responding to rapid changes in processor and accelerator demand. Fast-recovery diodes support high-frequency rectification and clamp functions, synchronous rectifier MOSFETs reduce secondary-side conduction loss, and medium-voltage step-down MOSFETs convert the intermediate bus into board-level rails. A separately protected fan-power path keeps cooling available during startup, service events and localized faults.
Designed for GPU servers, AI accelerators, high-performance computing and dense data-center racks
The architecture supports systems built around high-power GPUs, CPUs, custom accelerators, memory modules, storage and network interfaces. It is suitable for 48 V or 12 V server platforms where efficiency, transient response, thermal performance and fault containment directly affect computing availability and operating cost.
Device choices aligned with rectification, intermediate-bus conversion and cooling reliability
The MOT device mapping covers FRED diodes for rectification and clamp paths, low-voltage MOSFETs for synchronous rectification, medium-voltage MOSFETs for board-level buck stages, and load-switch MOSFETs for fan-power distribution. The placeholder products in this template should be replaced with verified MOT part numbers after voltage, current, package, thermal and switching requirements are confirmed.
