Abstract

An apparatus configured to measure a load current provided to a load of a switching converter includes a pulse generation circuit configured to generate a control pulse based on a power switch driving signal of the switching converter, a reference current generation circuit configured to generate a reference current based on the control pulse, a clock generation circuit configured to generate a clock signal based on the control pulse and the reference current, and a clock counter configured to count the number of cycles of the clock signal during a switching period of the switching converter. The reference current generation circuit is configured to adjust the reference current to compensate for a leakage current generated in the clock generation circuit during the switching period.
