ABSTRACT:
A CMC-type switching regulator is disclosed that includes: a switching element switching to control outputting of input voltage; a smoothing circuit outputting the smoothed output voltage of the switching element to an output terminal; a voltage divider dividing the output voltage; an error amplifier amplifying the difference between reference voltage and the divided voltage; a slope voltage generator generating slope voltage according to the reference voltage, correcting the slope of the slope voltage in accordance with the input-output voltage difference, detecting current flowing through the switching element and generating voltage according to the detected current, and outputting the generated voltage and the corrected slope voltage; a pulse generator outputting a pulse signal having time width according to the output voltages of the error amplifier and the slope voltage generator; and a switching controller controlling the switching of the switching element in accordance with the output signal of the pulse generator.
