A multi-phase synchronous converter consisting of a plurality of half bridges which in turn consist of an upper power switch and a lower power switch, the converter being actuated by a pulse width modulation dependent on a predetermined pulse duty cycle in the range of zero to one hundred percent. The multi-phase synchronous converter generates an output current and is operated in a normal mode in which the power switches switch with a normal switching period defined by a predetermined normal switching frequency, and a normal pulse duration dependent on the actual pulse duty cycle. As soon as the pulse duty cycle exceeds an upper duty cycle threshold or falls below a lower duty cycle threshold, the multi-phase synchronous converter is switched from the normal mode into an operating mode in which at least one of the power switches of at least one half bridge is deactivated.
