TI unveils power architecture for future AI data centres with NVIDIA
TI has unveiled a complete 800V direct current (DC) power architecture for next-generation AI data centres built with the NVIDIA 800 VDC reference design. The solution will be showcased at NVIDIA GTC, March 16-19, 2026, at NVIDIA’s power architecture display and TI’s booth 169, demonstrating how TI’s analog and embedded processing technology supports NVIDIA’s vision for advancing high-voltage systems in AI data centres.
As AI workloads continue to drive unprecedented power requirements in data centres, traditional power distribution architectures are reaching their limits. TI’s 800 VDC architecture addresses these challenges by maximising conversion efficiency and power density across the entire power path, simplifying the power architecture and enabling more scalable and reliable AI data centre operations.
TI’s breakthrough approach requires only two conversion stages from 800V to GPU core power: compact 800V to 6V isolated bus converter with higher peak efficiency, followed by a 6V to <1V multiphase buck solution with high current density generation-over-generation. This streamlined architecture supports the NVIDIA reference design.
TI’s 800 VDC power architecture solution shown at NVIDIA GTC includes multiple breakthrough reference designs with industry-leading specification:
● 800V hot-swap controller: Scalable hot-swap solution for input power protection for 800V rails
● 800V to 6V DC/DC bus converter: High density solution featuring integrated GaN power stages, delivering 97.6% peak efficiency with >2000W/in3 power density for compute tray applications
● 6V to <1V multiphase buck converter: High-current solution for advanced GPU cores, with higher power density vs 12V designs and featuring dual-phase power stages.
In addition to these designs, TI will showcase a 30kW 800V high power density AC/DC PSU for AI servers and 800V capacitor bank units (CBU) with 40W/in3 power density using EDLC super capacitor cells. TI will also be featuring an 800V to 12V DC/DC bus converter for compute tray power conversion.
