ABSTRACT:
A method regulates the time constant matching of a DC/DC converter phase, further to a variation of a load applied to an output of said phase. Such phase being associated with a coil network, with a series RL circuit and a reading network10, with a series RC circuit connected in parallel to the coil network. The method includes an acquisition step, suitable to acquire the trend of a voltage detected across the capacitance CDof the reading network10, transforming it into a current trend, a detection step suitable to identify a variation above a certain threshold value of said current trend, an identification step, enabled by said detection step, suitable to determine a slope of said current trend and a regulation step suitable to adapt the value of said resistance RDbased on said slope determined by said identification step.
