Critical bandwidth for the load transient response of voltage regulator modules

This paper investigates the relationship between the control bandwidth and the load transient response in voltage regulator modules (VRMs), which are designed with multiphase interleaving synchronous buck converters. Both voltage- and current-mode controls are discussed. A critical bandwidth value i...
