<p>A control circuit of a power supply unit, a power supply unit and a control method thereof are provided to enable to set and adjust a voltage value of an output voltage flexibly as to the instruction from the outside. A control circuit(20) of a power supply unit(1) controls a voltage value of an output voltage according to the instruction from the outside. A voltage regulation part(AD) regulates actual voltage information, according to first voltage setting information inputted from the outside, or the first voltage setting information and second voltage setting information. The voltage value of the output voltage is controlled on the basis of the actual voltage information outputted from the voltage regulation part.</p> |
