USA, Texas: Texas Instruments (TI) has announced its collaboration with NVIDIA to develop advanced power management and sensing technologies designed for 800 V HVDC distribution systems in AI-focused data centers.
This new approach marks a shift in how power is delivered to servers, enabling scalable and efficient solutions as AI computing demands continue to surge. With rack power consumption expected to grow from 100 kW today to over 1 MW soon, the limitations of traditional 48 V systems are becoming evident. A 1 MW rack using 48 V infrastructure would require nearly 450 pounds of copper, making it physically impractical for future expansion.
The shift to an 800 V HVDC architecture will offer greater power density and efficiency, while also reducing the size, weight, and complexity of power systems. This breakthrough enables data center engineers to design energy-efficient racks that can evolve with the increasing needs of AI applications.
“We are witnessing a fundamental transformation,” said Jeffrey Morroni, Director of Power Management R&D at Kilby Labs and a TI Fellow. “With NVIDIA’s AI expertise and our innovations in power conversion, we are enabling infrastructure that can support the extreme energy needs of future AI data centers.”
NVIDIA’s VP of System Engineering, Gabriele Gorla, added, “High-performance AI infrastructure depends on advanced semiconductor power systems. This partnership is central to developing efficient, large-scale solutions.”
