Texas Instruments (TI) has announced a collaboration with NVIDIA to develop new power management and sensing technology aimed at supporting future high-voltage power systems in AI data centres.
The partnership focuses on creating an 800-volt direct current (DC) power distribution system that will power NVIDIA’s next-generation AI servers. This new system is designed to make data centres more scalable, reliable, and efficient as demand for AI computing continues to rise.
“Semiconductor power systems are an important factor in enabling high-performance AI infrastructure. NVIDIA is teaming with suppliers to develop an 800V high-voltage DC architecture that will efficiently support the next generation of powerful, large-scale AI data centres,” Gabriele Gorla, vice president of System Engineering at NVIDIA, said.
With the growing use of AI, the power demand per data centre rack is expected to jump manifold in the near future. A 48V system would require heavy copper wiring—almost 205 kilograms per rack, making it impractical to scale power to support computing needs in the long term.
However, with Texas Instruments’ expertise and switching to an 800V high-voltage architecture, companies can deliver higher power with greater efficiency while keeping the equipment’s size and weight manageable. This shift will help engineers design data centres that can handle increased computing power without becoming more complex or bulky.“A paradigm shift is happening right in front of our eyes,” said Jeffrey Morroni, director of power management research and development at Kilby Labs and a TI Fellow. “AI data centres are pushing the limits of power to previously unimaginable levels. A few years ago, we faced 48V infrastructures as the next big challenge. Today, TI’s expertise in power conversion combined with NVIDIA’s AI expertise enables 800V high-voltage DC architectures to support the unprecedented demand for AI computing.”
