<p>PROBLEM TO BE SOLVED: To efficiently reduce power consumption when a device has made a transition to a power saving state.SOLUTION: A power source device includes a power source 300 that creates a first output voltage VCC1 from an AC voltage, a load switch 366 that supplies or interrupts the first output voltage VCC1 created by the power source 300 to a load, a control unit 400 that controls the connection or disconnection of the load switch 366, and a comparison circuit 398 that reduces, when the load switch 366 is disconnected by the control unit 400, the first output voltage VCC1 created by the power source 300 lower than a predetermined value.</p> |
