Abstract: A DC/DC converter and a series regulator are connected in parallel between an input terminal and an output terminal. At the time of a heavy load, the DC/DC converter is operated. Although the DC/DC converter has a large current consumption of its own, it has a high power conversion efficiency. Accordingly, since a load current increases at the time of a heavy load, it is effective to use the DC/DC converter whose power conversion efficiency is high, and its current consumption can be neglected since the load current is large. On the other hand, at the time of a light load, the series regulator is operated. Although the series regulator has a small current consumption of its own, it has a low power conversion efficiency. Accordingly, at the time of a light load, even when the series regulator is used, its low power conversion efficiency can be neglected because its current consumption is small.

Abstract: A first charge pump circuit and a second charge pump circuit are complementarily driven by a first driving circuit and a second driving circuit, and step up a DC input voltage by two times. Also, the first driving circuit stops its operation based on a light load judging signal, an input voltage judging signal or an output voltage judging signal, which is input in a control input terminal. For example, when the load is light, there is a margin for the load, and the light load judging signal becomes to be an “L” level. As a result, the first driving circuit stops outputting drive signals, such that the first charge pump circuit stops its operation.
