Abstract
A method for controlling a multiphase DC-DC converter with two or more phase circuits, each with a switch arranged to control an inductor current through an inductor, the phase circuit is arranged to generate a phase current contributing to a total current to be delivered to an output side of the multiphase DC-DC converter. The method includes switching two or more of the phase circuits in Boundary Conduction Mode to generate interleaved phase current pulses, with a period length and a nominal turn-on time period of the switch; and, in at least one of the two or more of the phase circuits being switched, and for successive phases, repeatedly adapting the turn-on time period for controlling the length of the pulses of the inductor current to minimise a difference from the period length.
