<P>PROBLEM TO BE SOLVED: To achieve desired starting order and stopping order of a plurality of DC-DC converters through a simple arrangement. <P>SOLUTION: A plurality of DC-DC converters CNV1, CNV2 and CNV3 are cascaded through a plurality of control signal lines used commonly for starting order control and stopping order control. Each of the plurality of DC-DC converters has an order control circuit for actuating the start processing as the prestage control signal line is activated and activating the post-stage control signal line as the start processing is completed, actuating the stop processing as the post-stage control signal line is inactivated, and inactivating the prestage control signal line as the stop processing is completed. <P>COPYRIGHT: (C)2008,JPO&INPIT |
