Data center power requirements are constantly increasing and traditional power systems are no longer sufficient to meet this growing demand. The power distribution chain, from the frontend AC-DC stage to the backend DC-DC power distribution, needs to deliver the best performance in term of efficiency, power density and ability to interface with the digital world. It must ensure an optimized usage of energy thanks to different strategies, such as workload redistribution, dynamic resource allocation or virtualization.

ST offers a full set of products and solutions to ensure the most optimized power design across all the distribution chain. Our digital and analog controllers combined with MOSFETs and drivers are key ingredients for implementing the most efficient and most dense AC-DC power delivery. On the backend DC-DC power distribution, ST offers advanced solutions for the Point-of-Load conversion and a recently developed innovative DC-DC conversion from the 48V DC supply.
