- Provided is a DC-DC converter including an inductor configured to store input energy, a ground switch configured to provide a ground path of the inductor in response to a first signal, an inductor switch connected in parallel to the inductor so as to maintain the energy stored in the inductor in response to a second signal, output switches configured to output the energy stored in the inductor as multi-output voltages in response to third signals, and a switch controller including a switch controller configured to determine cross regulation between the multi-outputs and generate the first to third signals for decreasing the cross regulation.
