Texas Instruments announced a complete 800 VDC power architecture designed for AI data centers built around NVIDIA’s 800 VDC reference design. The solution includes reference designs that achieve high conversion efficiency and power density across the entire power path, simplifying the architecture for AI workloads.
The architecture features a two‑stage conversion process: an 800 V to 6 V isolated bus converter that can reach up to 97.6 % efficiency, followed by a 6 V to <1 V multiphase buck stage that delivers high current density. The design supports NVIDIA’s reference architecture and is showcased at NVIDIA GTC 2026, where TI will demonstrate the power solution at booth 169.
The launch positions TI to supply the high‑voltage power needs of AI data centers, complementing its analog and embedded processing portfolio and expanding its presence in the rapidly growing AI infrastructure market. The 800 VDC architecture reduces copper usage and cable bulk, improving power distribution efficiency and enabling higher power densities—reported at over 2000 W/in³ for a 30 kW AC/DC supply.
Kannan Soundarapandian, Vice President and General Manager of High‑Voltage Power at TI, said the architecture “represents a critical breakthrough that enables data center operators to meet today’s power challenges while preparing for tomorrow’s AI workloads.” The move aligns with an industry trend, as other companies such as GE Vernova, Hitachi, and Vertiv also develop 800 VDC solutions in partnership with NVIDIA.
Prior to this launch, TI had announced design resources and power‑management chips to scale from 12 V to 48 V to 800 VDC in October 2025, including a white paper co‑authored with NVIDIA. The new architecture builds on that foundation, offering a more complete and integrated solution for AI factories.
The announcement underscores TI’s strategy to capture a share of the AI infrastructure market, where power demands are expected to exceed 1 MW in the next few years. By providing a scalable, efficient power platform, TI aims to support the growing need for high‑voltage power distribution in AI data centers.
