STMicroelectronics announced the addition of two new 800 VDC power‑conversion stages—800 VDC to 12 V and 800 VDC to 6 V—designed to support NVIDIA’s 800 VDC data‑center architecture. The new converters complement the previously introduced 800 VDC to 50 V stage, giving the company a complete set of solutions for gigawatt‑scale AI compute infrastructure.
The 12 V and 6 V stages deliver higher efficiency and reduce copper usage by bringing the 6 V bus closer to the GPU. This design lowers the number of conversion stages, cuts resistive losses, and improves power density and thermal performance in large‑scale training clusters and inference farms.
STMicroelectronics has not disclosed a specific commercial availability date for the new converters, but the company expects them to enter the market in the second half of 2026.
The product launch comes after STMicroelectronics reported Q4 2025 results of net revenues of $3.33 billion, a net loss of $30 million, and an EPS of $0.11 versus an estimate of $0.27. For FY 2025 the company posted net revenues of $11.80 billion and a net income of $166 million. In its Q1 2026 guidance, STMicroelectronics projected net revenues of $3.04 billion and a gross margin of 33.7%.
Marco Cassis, President of STMicroelectronics’ Analog, Power & Discrete, MEMS and Sensors Group, said, “With these new converters for 800 VDC power distribution, ST brings a complete set of solutions to support the deployment of gigawatt‑scale compute infrastructure with more efficient, scalable, and sustainable power architectures.”
No specific market reaction to the product launch has been identified. The announcement adds to STMicroelectronics’ growing portfolio of high‑voltage power solutions aligned with NVIDIA’s reference design, positioning the company to capture a share of the expanding AI data‑center market.
