Abstract
According to one embodiment, a power supply circuit includes a load switch, a switching control unit, a first control unit, and a second control unit. The load switch is connected to a power supply and switches between an ON state connecting the power supply to a load and an OFF state disconnecting the power supply from the load. The switching control unit outputs a first signal for controlling switching of the load switch between the ON and OFF states. The first control unit increases an output voltage of the load switch in a steady manner over a predetermined period of time when the load switch is switched to the ON state in response to the first signal. The second control unit causes a charging current to flow to the load switch after the first signal is output from the switching control unit.
