Summary:PROBLEM TO BE SOLVED: To provide a switch circuit that reduces the latency between the time when an energization start instruction is issued and the time when a switch element starts energization.SOLUTION: The switch circuit includes: a switch element which inputs first DC voltage from the outside to output a second DC voltage; an integration circuit which controls voltage gradient until the second DC voltage becomes equal to the first DC voltage; a feedback circuit which feeds back the second DC voltage; and an error amplifier which amplifies an error between output of the feedback circuit and output of the integration circuit. The switch element is controlled by output of the error amplifier.
