Abstract
A control circuit for generating a control signal to add phases to a multiphase voltage regulator. The control circuit includes an input for receiving an error correction voltage from an error amplifier of the multiphase voltage regulator and at least one output for providing a PWM control signal. Control circuitry generates at least one PWM control signal to add a phase to the multiphase voltage regulator responsive to a determination that the error correction voltage has exceeded a threshold level.
