Abstract
To provide a COT-controlled switching regulator capable of preventing an output voltage from excessively exceeding a desired voltage even though a light load is connected to an output terminal. A switching regulator of the present invention is configured to be equipped with a 100% DUTY detection circuit which detects a 100% DUTY at which a high-side switching element continues an on state for a prescribed time or more and outputs a detected signal to an output control circuit and to cause the output control circuit to turn off the high-side switching element when the output control circuit receives the detected signal therein.
