Abstract
A switching regulator includes an oscillation circuit for generating a triangular waveform signal having a predetermined frequency, a comparator compares the triangular waveform signal generated by the oscillation circuit with a voltage control signal commensurate with a voltage to be output so as to generate a pulse signal which goes high or low depending on a result of the comparison, and a driving circuit for selecting a portion of the triangular waveform signal generated by the oscillation responsive to the pulse signal generated by the comparator, so as to generate the drive signal for driving the switching element.
