Abstract

A multiphase voltage regulator includes a plurality of phases and a controller. Each phase is configured to output a phase current to a load through an inductor in response to a control signal input to the phase. The controller is operable to: generate the control signals input to the phases; set a switching frequency of the control signals to a first value; and change the switching frequency from the first value to a second value different than the first value if the load current changes repetitively at a frequency that is within a predetermined range of the first value of the switching frequency. A corresponding method of operating the multiphase voltage regulator is also provided.
