    • A power supply controller includes an analog to digital (A/D) converter that performs analog-digital conversion of an output voltage and outputs a digital signal, a deviation signal generator unit that generates a deviation signal from the digital signal and a standard voltage value serving as an output voltage target value, and a power controller unit that controls the output voltage based on the deviation signal. The power supply controller includes a conversion range setting unit that sets a range of the reference voltage into the A/D converter based on a first signal as the digital signal in a power supply startup period, and sets the reference voltage range into the A/D converter based on a second signal as the deviation signal or as a signal corresponding to the deviation signal in a steady state period.
