1. A method for regulating time constant matching of a DC/DC converter phase following a variation of a load applied to an output of said phase, said phase being associated with a coil network having an LR circuit connected in series and being connected to a reading network having an RC circuit connected in parallel to said coil network, the method comprising: an acquisition step that acquires a trend of a voltage detected across a capacitance of said RC circuit and transforms the voltage trend into a current trend; a detection step that identifies a variation over a threshold value in the current trend obtained from said acquisition step; an identification step, enabled by said detection step, that determines a slope of said current trend; and a regulation step that adapts a resistance value of said RC circuit according to said slope determined by said identification step.
