<P>PROBLEM TO BE SOLVED: To provide a DC-DC converter capable of reducing ground noise while accelerating the switching speed. <P>SOLUTION: A DC-DC converter comprises a smoothing capacitor that is connected between a first output terminal to which one end of a load is connected and a second output terminal to which the other end of the load is connected, and smooths an output voltage. The DC-DC converter further includes a choke coil having one end connected to one end of a battery. The DC-DC converter further includes a semiconductor integrated circuit that has a switch terminal to which the other end of the choke coil is connected, a first potential terminal connected to the first output terminal, and a second potential terminal connected to the second output terminal and the other end of the battery. <P>COPYRIGHT: (C)2013,JPO&INPIT |
