Methods and systems for operating a multiphase voltage regulator are described. The multiphase voltage regulator can include a plurality of power stages. A controller can be connected to the plurality of power stages. The controller can detect a number of activated power stages among the plurality of power stages. The controller can adjust a gain of a current sense feedback loop of the controller to control a load-transient response of the multiphase voltage regulator. The adjustment to the gain can be based on the number of activated power stages.
