Abstract:
1. A switching regulator which steps down or boosts an input voltage applied to an input terminal, and which outputs an output voltage stabilized to a predetermined target value via an output terminal, comprising: a plurality of switching transistors provided in parallel; an output circuit including an inductor, an output capacitor, and a rectifying device; a pulse modulator which generates a pulse signal with a duty ratio controlled such that the output voltage of the switching regulator approaches the predetermined target value; and a driver which distributes the pulse signal to the plurality of switching transistors, and which switches the plurality of switching transistors in a time divisional manner, wherein the driver comprises a divider configured to divide the pulse signal, and distributes a plurality of pulse signals thus divided to the plurality of switching transistors, and wherein the divider comprises:
