Abstract
A semiconductor device includes a modulator, a comparator, a pulse width setting circuit, and a driver. The modulator modulates a reference voltage to generate a reference signal. The comparator generates a comparator signal based on a result of comparing the reference signal and a feedback of an output signal supplied to an output terminal. The pulse width setting circuit generates a pulse modulation signal based on the comparator signal, wherein pulses of the pulse modulation signal have a pulse width that is equal to or greater than a predetermined pulse width. The driver outputs a driving signal that is based on the pulse modulation signal to the output terminal through an inductor.
