Abstract:
A step-down switching regulator that converts an input voltage to a predetermined lower output voltage which includes a first switch, an inductor, a second switch, a controller, and a detector to detect a proportional voltage of the output voltage and to output detection results to the controller when the proportional voltage exceeds a first predetermined reference voltage or falls below a second predetermined reference voltage which is lower than the first predetermined reference voltage. The controller shuts the first switch off when the proportional voltage exceeds the first predetermined reference voltage and shuts the second switch off when the proportional voltage falls below the second predetermined reference voltage.
