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 network 10, 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 C.sub.D of
the reading network 10, 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 R.sub.D
based on said slope determined by said identification step.
