Texas Instruments has introduced a complete 800 V direct current power architecture designed to meet the needs of next generation AI data centers built using Nvidia’s 800 V DC reference design.
Due to the significant growth of AI workloads across multiple sectors, AI data centers’ power distribution architectures are reaching the limit. The TI 800 V DC architecture maximizes conversion efficiency and power density by simplifying the architecture and allowing more scalable and reliable AI data center operations, TI said.
The architecture requires two conversion stages from 800 V to GPU core power. This supports Nvidia’s reference design, TI said.
"The exponential growth of AI computing demands a fundamental rethinking of how we deliver power in data centers," said Kannan Soundarapandian, VP and GM of high-voltage power at TI. "Our advanced 800 V DC architecture represents a critical breakthrough that enables data center operators to meet today's power challenges while preparing for tomorrow's AI workloads. By collaborating with NVIDIA, we're helping accelerate the deployment of AI infrastructure that can scale efficiently and reliably."
The 800 V DC power architecture demonstrated at the recent Nvidia GTC includes:
- 800 V hot-swap controller
- 800 V to 6 V DC/DC bus converter
- 6 V to less than 1 V multiphase buck converter
