<p>PROBLEM TO BE SOLVED: To reduce the size of a power supply while controlling the increase of power consumption. SOLUTION: The structure may be simplified and useless power consumption can be reduced as much as that it is no longer required to additionally provide a means for preventing inverse flow to the first input end of the DC current supplied via the second input end, as can be done in the related art by preventing inverse flow to the first input end (CP, CM) of the DC current supplied via the second input end (VDD, VSS) using a rectifying means 201. As a result, apparatus can be reduced in size while controlling increase of power consumption.</p> |
