In one embodiment, the present invention includes a regulator having a pulse width modulation (PWM) controller to generate a PWM control signal based on a voltage level of a load coupled to the regulator, a driver to provide a drive signal to a switching element of the regulator responsive to the PWM control signal, and a power saver coupled between the PWM controller and the driver to receive the PWM control signal and to output the PWM control signal to the driver at a reduced rate during an idle mode of the load.
