Zusammenfassung:	A DC stabilizing power supply device includes offset means for always shifting a slope voltage Vslp from the ground potential to the positive side by a predetermined offset voltage so that the lower limit level of the slope voltage Vslp is higher than the lower limit level of an error voltage Verr. With this configuration, it is possible to provide a DC stabilizing power supply device capable of appropriately controlling duty without causing oscillation of the entire system and an electric device using it.
