Abstract
A switching power converter with an input terminal configured to receive a first input voltage; an output terminal configured to provide an output current to a load, wherein the output current has a peak value and an average value; a power switch; a first loop coupled to the input terminal, wherein the first loop configured to generate a first output signal based on the first input voltage; a second loop configured to generate a second output signal based on the output current; a multiplier configured to generate a multiplying signal based on multiplying the first output signal with the second output signal; and a driving circuit configured to generate a driving signal based on the multiplying signal to control the power switch, so as to reduce the ratio between the peak value and the average value of the output current.
