Computers, data centers, and servers have become the backbone of our society. The heart of a computer is the Central Processing Unit (CPU). Power conversion in computer, data center, and server typically occurs in two stages: 120VAC to a 12VDC AC-DC conversion followed by a Voltage Regulator Module (VRM) which regulate the CPU voltages at 1.2V (varying from 0.8V to 1.6V) from 12VDC. The next generation CPU will require the VRM to achieve high efficiency, fast dynamic response and lower cost.

计算机、数据中心和服务器已经成为我们社会的支柱。计算机的核心是中央处理器（CPU）。计算机、数据中心和服务器中的电源转换通常分两个阶段进行：120 VAC到12 VDC AC-DC转换，然后是电压调节器模块（VRM），将CPU电压从12 VDC调节到1.2 V（从0.8 V到1.6 V变化）。下一代CPU将要求VRM实现高效率、快速动态响应和低成本。
