Navitas Semiconductor has introduced a new power delivery board that converts 800V directly down to 6V in a single step, removing the need for intermediate voltage stages. Built on its GaNFast technology, the solution is designed for next-generation AI servers and is being showcased at NVIDIA GTC 2026.
Traditional data center power systems typically use multiple conversion stages, first stepping high voltage down to an intermediate level (like 48V) before further reducing it for processors. Navitas’ approach skips this step, enabling direct high-to-low voltage conversion. This simplifies system design, reduces energy losses, and saves space within server racks.
The platform aligns with the shift toward 800V DC architectures for high-density AI computing, an approach supported by companies like NVIDIA. By cutting out extra conversion stages, the design improves efficiency and allows more compact power delivery closer to compute hardware.
The board delivers about 96.5% peak efficiency and operates at a high switching frequency of around 1 MHz. It also achieves high power density in a compact, low-profile form factor, making it easier to position near GPUs and shorten power delivery paths.
On the hardware side, the primary stage uses multiple GaN transistors in a stacked full-bridge setup with advanced cooling, while the secondary stage uses silicon MOSFETs to produce the final low-voltage output. The high switching frequency allows for smaller components and contributes to the overall compactness.
This platform is designed to support evolving AI server systems based on NVIDIA MGX, which focuses on improving compute density and efficiency. The board will also be presented at APEC 2026.
