Abstract
A control circuit in a switching regulator, the switching regulator including an inductor and a switching circuit configured to control a current passing through the inductor in response to a control signal, the control circuit configured to receive a feedback voltage of an output voltage of the switching regulator and receive the current passing through the inductor as a current sensing signal. The control circuit includes a first internal signal generator configured to generate a first internal signal based on the feedback voltage and a reference voltage, a second internal signal generator configured to generate a second internal signal based on the current sensing signal such that a base level of the second internal signal varies according to the feedback voltage and the reference voltage, and a comparator configured to output the control signal based on the first and second internal signals.
