Abstract: A current detection circuit included in a power supply detects a current flowing to an inductance element from a detection tap of an inductance element connected between an output terminal and an output of a first switching element. A control circuit included in the power supply controls a first control terminal of the first switching element and a second control terminal of a second switching element and calculates an output current flowing to a load based on the current detected by the current detection circuit.
