摘要：
A switching element is controlled by a control circuit. When the switching element is in an ON state, a coil current I.sub.L ramps up. When the switching element is in an OFF state, the coil current I.sub.L ramps down. If an output voltage V.sub.out is smaller than a predetermined output voltage value, a control circuit is informed of it. If the coil current I.sub.L rises to a peak current I.sub.LP set by a setting circuit, the control circuit is informed of it. The setting circuit sets the peak current I.sub.LP proportional to an input voltage V.sub.in. The control circuit sets the switching element in the ON state when the output voltage V.sub.out is smaller than the predetermined output voltage value, and sets the switching element in the OFF state when the coil current I.sub.L rises to the peak current I.sub.LP.
