Navitas and Nvidia Team Up for High-Efficiency AI Data Center Power Delivery

Introduction

Navitas Semiconductor has collaborated with Nvidia on power semiconductor solutions for next-generation 800 VDC architectures, targeting AI data centers and GPU racks.

The Partnership

The collaboration uses Navitas' GaNFast and GeneSiC product lines, which utilize gallium nitride (GaN) and silicon carbide (SiC) respectively.

The Product

The headline product is a direct 800 V-to-6 V DC-DC conversion board, designed to skip intermediate conversion stages and achieve peak efficiency of 96.5% to 97.5% at 1 MHz switching frequencies.

Benefits

The board targets power densities of up to 2,100 W/in³ and promises material savings through the 800 V approach, including up to 45% thinner wiring and a 45% reduction in copper needs.

The Impact

The partnership has unfolded with Navitas exhibiting the 800 V-to-6 V power delivery board at COMPUTEX and unveiling a joint reference design with Microchip.

Conclusion

The collaboration has significant implications for Navitas, Nvidia, and the AI infrastructure, with key factors to watch including adoption of the 800 V HVDC standard and the efficiency of real-world deployments.
