Abstract: A method of controlling a DC-DC converter having means for comparing the output voltage with a low threshold and a high threshold, means injecting a certain minimum electric charge into an inductor of the converter during a conduction phase of at least a power switch, comprises commanding the beginning of a conduction phase each time the output voltage drops below the low threshold, progressively increasing the electric charge transferred during a conduction phase by incrementing its duration until the output voltage rises to said high threshold, starting from said low threshold upon executing a single conduction phase, measuring and storing the duration of the time interval between two consecutive conduction phases, comparing the current time interval with the previously detected and stored time interval, decreasing the duration of the next conduction phase to correspond to said minimum electric charge whenever an increment of the time interval between two consecutive conduction phases is detected.
A hardware implementation is also described.
