PROBLEM TO BE SOLVED: To provide a power supply device, a power supply control method, and a power supply control program capable of controlling a power-on and power-off sequence of the power supply device efficiently with a small processing load.SOLUTION: The power supply device includes: a plurality of power supply voltage generation means which generates a power supply voltage by digital control on the basis of set data; first storage means having sequence data stored therein which is the data for a sequence according to which the power supply voltage is generated by the plurality of power supply voltage generation means and generation of the power supply voltage by the plurality of power supply voltage generation means is stopped; sequence control means which, by using the sequence data, controls generation of the power supply voltage and stoppage of voltage generation following the sequence; and clock generation means which generates two kinds of clocks differing in frequency. The sequence control means uses a lower frequency clock out of the two kinds of clocks to control generation of the power supply voltage and stoppage of voltage generation following the sequence, and uses a higher frequency clock out of the two kinds of clocks to control generation of the power supply voltage and stoppage of voltage generation in software. |
