Abstract:
The present invention is a switching regulator in which a MOS transistor Q1 (first switch) and a MOS transistor Q2 (second switch) are complementarily turned on/off according to an output voltage VOUT, and in which a MOS transistor Q3 (third switch) and a MOS transistor Q4 (fourth switch) are complementarily turned on/off by fixing an on-duty D of the MOS transistor Q3 (third switch) in a step up/down mode. The switching regulator controls an electrical current mode according to information about an electrical current flowing in the second switch.
