ABSTRACT:
Multiple switching transistors are provided in parallel. An output circuit includes an inductor, an output capacitor, and a rectifying device. A pulse modulator generates a pulse signal with the duty ratio adjusted such that the output voltage of a switching regulator approaches a predetermined target value. A driver distributes a pulse signal to the multiple switching transistors, and switches the multiple switching transistors to the ON state in a time divisional manner.
