Classification: CPC H | IPC H

Claim 11:
12. A switching converter configured to generate an output voltage from an input voltage, the switching converter comprising:
an inductor and an output capacitor connected to an output node from which the output voltage is generated;
a first power switch and a second power switch configured to provide an inductor current to the inductor;
a switch driver configured to generate a power switch driving signal for controlling the first power switch and the second power switch; and
a load current meter configured to measure a load current provided to a load of the switching converter,
wherein the load current meter is configured to generate a control pulse based on the power switch driving signal of the switching converter, is configured to generate a reference current based on the control pulse, is configured to control the reference current to compensate for a leakage current generated in a clock generation circuit, is configured to generate a clock signal corresponding to the load current based on the control pulse and the reference current, and is configured to count a number of cycles of the clock signal during a switching period of the switching converter.
