According to one embodiment, a turbo circuit for increasing an output of a voltage regulator having a several power stages includes an activation sub-circuit coupled to a feedback signal of the voltage regulator, the activation sub-circuit being configured to generate a multi-stage ON signal for turning on the power stages substantially concurrently. The turbo circuit further comprises a deactivation sub-circuit coupled to the feedback signal, the deactivation sub-circuit being configured to cancel the multi-stage ON signal when the feedback signal reaches an extremum value. In one embodiment, the turbo circuit may be implemented in a multi-phase buck converter fabricated as part of an integrated circuit on a semiconductor die. In another embodiment, the turbo circuit can be implemented in a multi-phase boost converter as part of an integrated circuit on a semiconductor die.
