Abstract: A power converter which has a reservoir capacitor, a first flying capacitor, and first and second inductors coupled to a network of switches is presented. A driver is adapted to drive the network of switches with a sequence of states during a drive period. The power converter is operable in a first mode to deliver an output current using both the first and second inductors and a second mode to deliver the output current using the first inductor and without using the second inductor. When a load current is above a threshold value, the driver drives the network of switches in a first sequence of states to operate the power converter in the first mode. When the load current is equal or below the threshold value, the driver drives the network of switches in a second sequence of states to operate the power converter in the second mode.
