Abstract
The invention concerns a detector of overloads for DCDC converters, the said converter supplying a load current with an output voltage (Vout) that may be different from a supply voltage (Vbat), by means of an inductance (L) and a first transistor (TP0), made conductive or blocked by regulation devices depending on the quantity of current demanded by the said load, the said detector having a means of capturing an image of the said load current at a predetermined smaller scale, and also a means of analysis that takes into account the said load current image to provide overload information when the said quantity of current is higher than a predetermined current threshold.
