Abstract
An electronic device includes a first switching element connected between a power source and one end of a power inductor, a second switching element connected between the one end of the power inductor and ground, a detection unit that detects a current flowing to the second switching element when a period in which the first switching element is in an off-state and the second switching element is in an on-state, and a control unit. The control unit uses the detected current to gradually decrease an on-resistance of the first switching element, when the first switching element is changed from the off-state to an on-state, and uses the detected current to gradually increases an on-resistance of the second switching element, when the second switching element is changed from the on-state to an off-state.
