Powering the AI Core: Power Integrations Optimizes NVIDIA's Data Center Blueprint

Power Integrations (POWI) is setting a new standard for high-density computing infrastructure by unveiling ultra-slim reference designs optimized for the NVIDIA Kyber 800 VDC AI data center architecture.

Breaking the 800V Energy Barrier via GaN Innovation

The company's newly released 15 W and 35 W auxiliary power supply designs leverage 1700 V-rated PowiGaN technology, eliminating the bulkiness associated with traditional discrete silicon carbide solutions. This innovation enhances operational sustainability by minimizing energy loss during the management of critical data center control functions.

■High-performance architecture maintaining at least 88% efficiency.

■Seamless power delivery for gate drivers and MCUs via InnoMux-2 IC integration.

■Single-HEMT GaN technology ensuring wide safety margins on 800 V buses.

Slashing BOM and Spatial Constraints by 30%

By streamlining the design of liquid-cooled blade-rack systems, these reference modules enable engineers to build more compact and dense AI infrastructures. In data center environments where space is at a premium, the reduction in component size translates directly into financial advantages.

■30% reduction in board space and bill of materials (BOM) costs.

■A more reliable and compact foundation for demanding high-voltage environments.

■Full integration capability with NVIDIA's next-generation data center architecture.

The reduction in the physical volume of high-density AI servers directly impacts the global supply chain logistics of these critical assets. As compute power per unit increases while volumetric weight decreases, tech giants can optimize their air freight operational costs and shorten delivery lead times. This "slimming down" of hardware translates to higher shipment capacity across the global air bridge, reducing the logistical friction of scaling AI infrastructure.
