Navitas Semiconductor saw its stock surge roughly 25% on Wednesday after the company announced collaboration with the NVIDIA MGX Ecosystem aimed at accelerating 800 VDC AI infrastructure.
Navitas participated in NVIDIA’s Partner Ceremony on May 29, 2026, at the Taipei Nangang Exhibition Center. That event gathered ecosystem partners supporting the NVIDIA AI Factory MGX platform, which is designed for next-generation AI data centers built around 800 VDC rack architectures.
At COMPUTEX 2026 in Taipei, running June 2-5, Navitas is presenting an 800 V-to-6 V DC-DC power delivery board in NVIDIA’s AI Factory MGX Ecosystem Showcase. The board uses Navitas’ GaNFast technology and, according to the company, removes the need for a conventional 48 V intermediate bus converter stage within compute server trays.
Technical details provided by the company outline a design that employs 16 GaNFast FETs rated at 650 V with on-resistance of 11 mOhms. Navitas says the board targets a 97.5% peak efficiency while operating at a 1 MHz switching frequency. The design is described as enabling a power density of 2100 W/in3 and being approximately 20% thinner than a mobile phone.
"As AI workloads continue to scale and drive unprecedented demand for compute, power delivery has become one of the most critical challenges in enabling next-generation gigawatt AI factories," said Chris Allexandre, President and CEO of Navitas.
Navitas supplies gallium nitride (GaN) and silicon carbide (SiC) power semiconductors. The company’s GeneSiC silicon carbide portfolio includes products for solid-state transformers with 2300 V and 3300 V SiC power modules, and high-power three-phase power supply units using Generation 5 technology 1200 V SiC MOSFETs.
Summary and context - Navitas’ participation in NVIDIA’s MGX Ecosystem and the COMPUTEX showcase highlights the company’s push to position GaN-based power delivery as a solution for 800 VDC rack architectures that are being promoted for next-generation AI data centers. The firm’s demonstration claims emphasize compactness, high power density and high peak efficiency.
Key points
- Navitas stock rose about 25% following the collaboration announcement with NVIDIA’s MGX Ecosystem.
- The company is displaying an 800 V-to-6 V GaNFast DC-DC board at COMPUTEX 2026 that aims to remove the traditional 48 V intermediate bus converter stage in server trays.
- The board is specified to use 16 GaNFast FETs (650 V, 11 mOhms), target 97.5% peak efficiency, operate at 1 MHz, and achieve 2100 W/in3 power density while being roughly 20% thinner than a mobile phone.
Risks and uncertainties
- The announcement does not provide independent verification of the board’s efficiency or availability for production-scale deployment.
- The company’s statements leave unspecified timelines for commercial adoption within AI data centers or broader deployment across server manufacturers.
- The article does not detail integration, interoperability or qualification steps required for replacing a 48 V intermediate bus converter in existing server architectures.
Taken together, the disclosure of technical targets, the showcase at COMPUTEX and participation in NVIDIA’s MGX partner event have coincided with a notable market reaction for Navitas, while the announcement leaves open questions about verification and deployment timelines.
