Abstract
A switching circuit includes: a switching section including at least one first terminal, a plurality of second terminals, and a switching element configured to connect the first terminal to one of the second terminals; a driver driving the switching element in accordance with an external terminal switching control signal; a DC-to-DC converter, which supplies electric power to the driver, having a first state with a response to a load transient and a second state with the response to a load transient being slower than the first state; and a power controller controlling the DC-to-DC converter to operate with the first state during a first time period corresponding to change in the external terminal switching control signal, and to operate with the second state during a second time period other than the first time period.
