Abstract
A switching converter includes: a power stage circuit which includes at least one switch to switch an inductor to convert an input power to an output power; a first loop control circuit configured to switch the at least one switch by a peak current mode according to a first feedback signal related to the output power and an inductor current of the inductor in a first control mode; and a second loop control circuit configured to control the at least one switch to switch with a switching period according to a second feedback signal in a second control mode. If the power stage circuit operates in DCM during consecutively more than a predetermined number of the switching periods, the switching converter enters the first control mode. A portion of sub-circuits of the second loop control circuit are turned off to reduce power consumption in the first control mode.
