<p>PROBLEM TO BE SOLVED: To provide a DC-DC converter that reduces a ripple voltage.SOLUTION: In the DC-DC converter, for generating a positive voltage, a control circuit controls first to fourth switch circuits with first to fourth control signals to establish a continuity between a first node and a first reference node and establish a continuity between an eighth node and a fourth reference node, then establish a continuity between a fourth node and a second reference node and establish a continuity between a sixth node and a third reference node, and thereafter establish a continuity between a second node and the first reference node.</p> |
