DROOP法实现CPU负载电压调节的设计

摘要

本文通过对输出电感DCR电流信号采样、运算,采用Droop法调节计算机处理器负载电压.经测试证明该方法满足1毫欧负载线斜率的设计要求.%The Droop method is used in this paper to regulate the output voltage of CPU in the mother board. A current sensing method is introduced to get the current signal which is evaluated according to the 1mΩ load line slope with OPs.
