Abstract
This paper presents a double-loop relay feedback scheme for voltage regulator modules (VRM). The relay feedback control is designed to stabilize the VRM and also to achieve good regulation and fast dynamics. The stability and performance of the presented relay feedback control are analyzed. Also, a 12V/1.5V VRM with proposed control is designed and simulated, which shows an output regulation with 0.33% steady-state output error and 4% load regulation error in response to the load current steps from 65A/1A to 1A/65A, at a slew rate of 6OA/g=m/sec.
