Navitas Unveils Breakthrough 10 kW DC-DC Platform Delivering 98.5% Efficiency for 800 VDC Next-Gen AI Data Centers
Navitas Semiconductor, a leader in GaNFast™ gallium nitride (GaN) and GeneSiC™ silicon carbide (SiC) power semiconductors, unveiled a breakthrough 10 kW DC-DC power platform delivering up to 98.5% peak efficiency and 1 MHz switching frequency, enabling unprecedented power density to support the rapid, large-scale expansion of next-generation AI data centers.
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% peak efficiency and 98.1% 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 centers.

Comments
“The design platform enables the transition to HVDC data center 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 center 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 center customers through collaborative development and will make its debut at the Navitas booth (#2027) at APEC, March 22–26 in San Antonio, TX.
