<P>PROBLEM TO BE SOLVED: To provide a DC/DC converter that outputs a constant current or a constant voltage depending on a load. <P>SOLUTION: A switching-system DC/DC converter performing feedback control of an output voltage by a pulse width modulator, has means of decreasing the output voltage when an output current becomes a specified value or more, and increasing the output voltage when the output current becomes the specified value or less, depending on the output current to be supplied to a load from the DC/DC converter. <P>COPYRIGHT: (C)2012,JPO&INPIT |
