Patent ID: 10423210

Abstract:
A multiphase voltage regulator (VR) has a VR controller that performs automatic VR phase assignment and configuration for single or multi-output rails of an Information Handling System (IHS). VR power circuit has power stages selectably coupled to output voltage connection(s) or rail(s) that deliver electrical energy to information handling resource(s). VR controller is coupled to the VR power circuit and provides a first reference voltage (IREF) signal to the VR power circuit. VR controller identifies any power stages that return a load current monitor (IMON) signal that indicates that the respective power stage is coupled to the first IREF signal. VR controller regulates identified power stages of the VR power circuit during delivery of electrical power to information handling resource(s). Regulation is according to a VR configuration that is selected based on identified VR phases assigned to a first output voltage loop and associated with the first IREF signal.
