Navitas unveils 10 kW DC-DC platform
Navitas Semiconductor has unveiled what it describes as a breakthrough 10 kW DC-DC power platform delivering up to 98.5 percent peak efficiency and 1 MHz switching frequency, enabling unprecedented power density to support the rapid, large-scale expansion of next-generation AI data centres.
The all-GaN 10 kW 800 V–to–50 V DC-DC platform employs advanced 650 V and 100 V GaNFast FETs in a three-level half-bridge architecture with synchronous rectification to deliver 98.5 percent peak efficiency and 98.1 percent full load efficiency in a full-brick (61 × 116 × 11 mm) package, achieving 2.1 kW/in³ power density.
The resulting production-oriented platform supports 800 V–to–50 V and + / – 400 V–to–50 V architectures at 10 kW, integrating auxiliary power and control to simplify adoption and enable high–power-density module designs for next-generation HVDC AI data centres.

“The design platform enables the transition to HVDC data centre power infrastructure, supporting the future power requirements of AI workloads that will demand between 100- and even 1,000-times more compute per query,” said Chris Allexandre, president and CEO of Navitas Semiconductor. “Navitas continues to redefine what’s possible in AI data centre power, with the 10 kW DC-DC solution giving breakthrough efficiency, power density, and scalability to allow faster and cooler operation while making them more sustainable.”
The 10 kW DC-DC platform is being evaluated by key data centre customers through collaborative development and will make its debut at the Navitas booth at APEC, March 22–26 in San Antonio, US.
