Abstract
Methods and systems are disclosed that may be employed to enable multi-phase voltage regulator (VR) system calibration during the development phase of a multi-phase VR system so as to meet defined accuracy targets and, in one example, to avoid the need for system level calibration in a production environment. The disclosed systems and methods may be further implemented to enable use of multiple sources for and types of integrated power stages (IPstages) in a common multi-phase VR system configuration while still achieving the required current sense accuracy, thus reducing or substantially eliminating continuity of supply (COS) concerns.
