Abstract
According to certain aspects, the present embodiments are directed to techniques for providing the ability to monitor one or more operational parameters of a voltage regulator. In embodiments, the voltage regulator is a multiphase voltage regulator having a plurality of power stages corresponding to each respective phase. In these and other embodiments, the operational parameters include one or both of a phase current and a phase temperature. According to certain additional aspects, the present embodiments provide the ability to monitor the respective phase current output and phase temperature of each phase independently. According to further aspects, this ability to monitor the operational parameters is achieved while minimizing circuit complexity.
