Original Abstract Submitted
A DC/DC converter including a low side and a high side is disclosed. The converter includes a first switching device being part of the low side, a low side current generator configured to generate a low side current flowing in the first switching device, a second switching device, a compensation resistor coupled in series to the second switching device, a valley current reference current generator configured to generate a valley current threshold current (I) flowing in the second switching device and in the compensation resistor for obtaining a first voltage value, and a comparator configured to compare the first voltage value and a reference voltage for generating an error signal as a function of the comparison, the error signal controlling a conductivity of the first switching device of the low side.
