数据中心的电力需求持续上升，传统的电力系统已经不能满足这种不断增长的需求。从前端交流-直流（AC-DC）到后端直流-直流（DC-DC）配电的配电链，需要在效率、功率密度和与数字世界的连接能力方面提供最佳性能。由于采用工作负载再分配、动态资源分配或虚拟化等不同的策略，它必须确保能源的优化使用。

ST提供全套的产品和解决方案，确保在整个配电链范围内实现最优的电力设计。我们的数字和模拟控制器结合MOSFET和驱动器，是实现最有效和最密集的交流-直流（AC-DC）电力传输的关键要素。在后端直流-直流（DC-DC）配电方面，ST提供先进的负载点转换解决方案，以及最近开发的创新型（从48V直流电源进行）直流-直流（DC-DC）转换技术。
