A control circuit for use in controlling a phase of a multi-phase voltage converter in accordance with an embodiment of the present invention includes a driver operable to provide a first control signal to a high side switch of a half-bridge of the phase and a second control signal to a low side switch of the half bridge, such that a desired output voltage is provided by the phase, current sensing circuitry operable to detect the output current of the phase, a comparator operable to compare the output current to a threshold current value and a disabling device operable to provide an enable/disable signal to disable the driver when the output current is below the threshold current value.
