摘要： A method of measuring a load current provided to a load of a switching converter includes obtaining a first reference voltage defining a peak of an inductor current passing through an inductor of the switching converter, generating a pulse based on the first reference voltage and an on-time of at least one power switch of the switching converter, generating an output signal by filtering the pulse, and setting a second mode from a first mode when a value of the load current is less than a first threshold value based on the output signal. The generating of the pulse further includes generating the pulse having a width extended in proportion to the on-time in the second mode.
