Scalable ISOP GaN Power Solutions for AI Data Centers and HPC

Future-Proof Power for the AI Era

AI factories and high-performance computing are driving server rack power toward the megawatt scale. From today’s 400 V server platforms to next-generation 800 V AI “factories,” using a modular Input-Series-Output-Parallel (ISOP) topology, GaN delivers the high efficiency, density, and simplicity needed to power next-generation AI servers.

Key Benefits of the ISOP Topology:

  • Higher Power Density: 6 kW in a compact, 8-mm high form factor for space-constrained AI boards
  • Reduced Bussing Losses: Converts 800 V directly to 12.5 V near the load, cutting copper loss and cost
  • Simplified Cooling: Top-side cooled design with evenly distributed thermal load
  • Lower Cost: Standard off-the-shelf components
  • Scalable Architecture: Modular ISOP configuration supports future gigawatt-scale AI ‘factories’.

Scalable ISOP Power Architecture – From 400 V to 800 V

The ISOP architecture forms a unified platform adaptable to multiple voltage domains.

Design Input / Output Power Height Efficiency Topology
EPC91110 400 V arrow_forward 50 V 5.5 – 6 kW 12 mm > 97 % 4× LLC ISOP
EPC91123 800 V arrow_forward 12.5 V 6 kW 8 mm > 97 % 8× LLC ISOP

EPC91110 proved the ISOP concept for existing 400 V data center power shelves.
EPC91123 takes the next step—doubling voltage, halving footprint, and enabling direct-to-board 12.5 V conversion for AI infrastructure.

Same architecture. Higher voltage. Higher power density.
