STMicroelectronics has launched new power conversion solutions, including 800-volt direct current (VDC) to 12V and 800 VDC to 6V converters, developed on the Nvidia reference design, for artificial intelligence (AI) data centres.
As per STMicroelectronics, the rapidly emerging 800 VDC data centre architecture enables higher energy efficiency, reduces power losses, and supports more scalable, high compute density infrastructure for hyperscalers and AI compute workloads. The expansion to 12V and 6V output stages reflects an industry shift towards different server architectures requiring varied power delivery configurations depending on graphics processing unit (GPU) generation, server height, form factor, and thermal envelope for large-scale training clusters, inference farms, and high-density AI infrastructure.
Further, the 50V, 12V, and 6V intermediate direct current buses will coexist in AI data centres depending on rack density, GPU configuration, and cooling strategy. The new 800 VDC to 12V converter enables high-efficiency power distribution from rack-level power shelves directly to the voltage domains that feed advanced AI accelerators. This new path allows vendors to reduce the number of conversion stages and move the 6V bus closer to the GPU. This reduces copper usage, minimises resistive losses, and improves transient performance, which is a critical differentiator for large-scale training clusters.
