Overview of the 800V AI Power Revolution

As artificial intelligence infrastructure pushes conventional power delivery architectures to their absolute limits, a new engineering approach is emerging to meet the escalating energy demands of AI factories. Navitas Semiconductor has unveiled a groundbreaking 24kW, 800V-to-12V DC-DC power delivery board developed in strategic collaboration with NVIDIA. This platform, powered by Navitas’ GaNFast gallium nitride (GaN) technology, is designed to support the NVIDIA MGX ecosystem. The board is being showcased at the 2026 Open Compute Project (OCP) Global Summit in San Jose, California, taking place from October 12 to 15, 2026, marking a critical step toward high-voltage direct current (HVDC) power architectures for next-generation AI data centers.

Technical Details of the 24kW Power Board

The newly announced board is engineered to deliver 24kW of power directly to the compute tray. It targets a full-load efficiency of 97%, meaning that at 24kW of output, the approximate input power would be 24.74kW, with around 742W dissipated as conversion losses. Furthermore, the board targets a power density exceeding 2,000 watts per cubic inch. Designed around a compact 400mm × 60mm form factor specified by NVIDIA, it integrates onto the compute motherboard close to the xPUs to shorten power-delivery paths. The primary side incorporates 16 NV6034 GaNFast field-effect transistors, rated at 650V and 18 milliohms. These devices are configured in a stacked half-bridge topology and utilize Navitas’ dual-cooled DFN 8 × 8 package.

The Shift to High-Voltage Direct Current Architectures

Traditional power distribution approaches face mounting pressure as AI systems require higher power within constrained physical footprints. High-voltage DC architectures offer a vital pathway to address these challenges by enabling more efficient power distribution and reducing the complexity associated with multiple conversion stages. This new 24kW board extends Navitas’ previously announced 20kW, 800V-to-6V power delivery board, also developed with NVIDIA. Together, these platforms illustrate the importance of architectural flexibility. Different intermediate-bus voltages and voltage regulator module (VRM) configurations are necessary to suit varying processor platforms and point-of-load requirements, ensuring the entire power chain can deliver required current and respond to rapidly changing workloads.

Wide-Bandgap Semiconductors Driving the Transition

This shift toward 800V power delivery creates significant opportunities for semiconductor manufacturers across several technology categories. Gallium nitride (GaN) offers high-speed switching capabilities, reducing power-conversion losses and component size, which is evident in the board's GaNFast implementation. Additionally, Navitas’ portfolio includes GeneSiC silicon carbide (SiC) technology, providing high-voltage power switching suited to demanding distribution applications. The integration of these wide-bandgap semiconductors reflects a system-level evaluation where semiconductor performance, board design, thermal management, and computing architecture must operate in unison. Advanced power packaging and next-generation power architectures are bringing power conversion closer to processors, drastically reducing distribution losses.

Implications for AI Data Center Efficiency

For AI data centers, the implications of this 24kW board extend far beyond component-level improvements. Achieving a 97% efficiency target is critical; even a small percentage improvement significantly reduces cooling requirements and facility-level energy consumption. The board's power density of over 2,000W/in³ allows designers to allocate more physical space to computing hardware. However, achieving this density places greater demands on thermal design, component integration, and reliability engineering. As accelerated computing platforms scale, power consumption rises alongside the need for faster interconnects and more sophisticated cooling, making efficient electricity delivery just as important as computational performance itself.

Future Outlook and Industry Impact

Navitas has positioned its 800VDC portfolio to provide customers with the flexibility to select intermediate-bus voltages and VRM architectures tailored to their specific applications. This flexibility will become increasingly valuable as AI infrastructure migrates across different accelerator generations, rack configurations, and computing platforms. By positioning itself across both GaN and SiC wide-bandgap semiconductor platforms, Navitas is equipped to address diverse device and system requirements. Ultimately, the 24kW board demonstrates how wide-bandgap technology can be successfully incorporated into power subsystems designed for advanced computing hardware, setting a new frontier for data center efficiency in the AI era.
