description In a power supply device (1) including a switching element (12) and a control section (11) configured to control the switching element (12), the control section (11) receives an input of a first signal fluctuating according to an output voltage of the power supply device (1) and fixed with respect to an input voltage of the power supply device (1) and a second signal, the amplitude of which fluctuates according to the input voltage of the power supply device (1), and controls ON or OFF of the switching element (12) according to time until a value of the second signal reaches a value of the first signal.
