Solving the Data Center Space Crunch: New 800 VDC Power Designs for AI Infrastructure
In the race to scale AI data centers, every millimeter of board space is critical. As power architectures shift to 800 VDC to support high-performance AI racks like the NVIDIA Kyber architecture, auxiliary power supply design has become a significant bottleneck.
Power Integrations has just announced a major step forward, unveiling two ultra-slim auxiliary PSU reference designs that address these high-voltage challenges head-on.
What makes these designs a game-changer? By leveraging their industry-unique 1700 V PowiGaN™ (Gallium Nitride) single-HEMT technology, they’ve managed to create incredibly dense power solutions that outperform traditional silicon carbide (SiC) approaches:
🔹 Space-Efficient: Freeing up ~30% of space on main power distribution boards (PDBs).
🔹 Simplified BOM: ~30% reduction in component count, boosting overall system reliability.
🔹 High Efficiency: Delivering at least 88% efficiency across line and load.
🔹 Low Profile: Ultra-slim form factors (down to 7mm height) ideal for tight blade-rack architectures.
These designs use InnoMux™-2 ICs to support a nominal 1000 VDC input, providing stable power for the "housekeeping" components—like MCUs, gate drivers, and op-amps—that keep AI systems safe and efficient.
For engineers working on the next generation of AI-ready data center infrastructure, this is a massive leap in simplifying high-voltage design.
