摘要： A switching power supply includes a switching element, a constant current element, a rectifying element, a first inductor, a second inductor, and a control circuit. If the switching element is on, the switching element supplies a power supply voltage to the first inductor and feeds an electric current. The constant current element turns off the switching element if the electric current of the switching element exceeds a predetermined upper limit. The rectifying element feeds the electric current of the first inductor if the switching element is turned off. The second inductor supplies the induced potential to a control terminal of the switching element. The control circuit supplies a pulse-like potential to a control terminal of the constant current element and outputs if an average of the potential is lower than a lower limit.

摘要： Disclosed is an interface circuit including a rectifier circuit, a detection circuit, a first circuit, and a second circuit. The rectifier circuit rectifies an AC voltage input between a pair of input terminals. The detection circuit detects the AC voltage and outputs the result as a detection voltage. The first circuit is controlled to be turned on or off on the basis of an input first control signal, to cause a first current to flow between the input terminals in an on state and to cut off the first current in an off state. The second circuit is controlled to be turned on or off on the basis of an input second control signal, to allow a second current greater than the first current to flow between the input terminals in an on state and to cut off the second current in an off state.
