| Zusammenfassung: | A direct-current stabilized power supply apparatus according to the present invention includes offsetting means that keeps a slope voltage (Vslp) shifted from the ground potential to a higher potential by a predetermined offset voltage V so that the lower limit level of the slope voltage (Vslp) is higher than that of an error voltage (Verr). With this configuration, it is possible to provide a direct-current stabilized power supply apparatus that can appropriately control a duty ratio without causing oscillation or the like in the overall system, and also to provide an electrical device incorporating such a power supply apparatus. |
