Abstract:
1. A detecting device for detecting a distribution profile of an output current of a switching converter configured to supply the output current, said detecting device comprising: a signal converter configured to convert a signal indicating the output current of the switching converter into a digital signal comprising a plurality of digital samples, and to process the digital samples into successive time intervals belonging to a time period; and a signal processor operably coupled to the signal converter, and configured to process each sample of the plurality of samples by comparing the sample with a plurality of n reference currents, n being an integer, the plurality of n reference currents having values successively increasing from a first reference current of the plurality of n reference currents to a last reference current of the plurality of n reference currents, the signal processor including a plurality of n counters associated respectively with the plurality of n reference currents, the signal processor being further configured to process each sample of the plurality of samples by incrementing a single i-th counter of said plurality of n counters for each sample of the plurality of samples, i being an integer between 1 and n, if the sample has a higher value than an i-th reference current of the plurality of n reference currents but lower than an i+1-th reference current of the plurality of n reference currents.
