Abstract
A switching converter with adaptive constant on-time control has a power switch and a control circuit. The switching converter converts an input voltage into an output voltage. When the switching converter is in a light-load state, the on-time of the power switch is controlled to be smaller than the on-time of the power switch in a normal-load state, wherein the normal-load state includes a continuous current mode (CCM) or a discontinuous current mode (DCM).
