Abstract
A switching regulator includes a power converting unit and a switch driving unit. The power converting unit is configured to generate a direct current (DC) output voltage based on a switch driving signal and a DC input voltage. The switch driving unit is configured to generate a ripple voltage having information of an inductor current flowing through the power converting unit, add the ripple voltage to a reference voltage to generate a first voltage having a ripple, generate a feedback voltage based on the DC output voltage, compare the first voltage with the feedback voltage in a hysteresis mode to generate a comparison output, and generate the switch driving signal based on the comparison output.
