Abstract

A current detecting circuit includes a first switching element, a second switching element, and a third switching element electrically coupled in series with the first switching element. An output side of the third switching element is electrically coupled to an output terminal. The current detecting circuit includes a current amplifier configured to detect a difference between a first output voltage of the first switching element and a second output voltage of the second switching element. The current amplifier outputs a relative current to be used for detecting an output current that flows out from the output terminal. A ratio of resistance associated with the first switching element to resistance associated with the second switching element is n:1.
