Abstract
The present disclosure provides a switch device. The switch device includes a switch element, a DA converter and output voltage control unit. The switch element includes: a first end to which an input voltage is applicable; a second end to which an output voltage is applicable; and a control terminal. The output voltage control unit includes the switch element and configured to control the output voltage. The output voltage control unit is configured to generate a control voltage applicable to the control terminal such that the output voltage is gradually increased according to a ramp-like change in an output of the DA converter.
