PROBLEM TO BE SOLVED: To provide a power supply start controller allowing users who develop an apparatus to arbitrarily change start timing of each power supply circuit without revising a LSI mask.SOLUTION: A sequence circuit 5 controls the start timing of each of power supply circuits 1 to 4 on the basis of count setting values CONT1 to CONT4 which are output from a selection circuit 7 for the power supply circuits 1 to 4. A timing setting circuit 8 outputs predetermined count setting values C81 to C84. An interface circuit 9 reads predetermined start control data 31D that is stored in an external storage device 31, and outputs it as count setting values C91 to C94. In response to a selection signal SEL, the selection circuit 7 outputs the count setting values C81 to C84 or the count setting values C91 to C94 to the sequence circuit 5 as the count setting values CONT1 to CONT4. |
