摘要： An apparatus is provided which comprises: at least two switches in series between an input voltage node and a ground terminal; an inductor coupled between a mid-point of the at least two switches and an output terminal; a first circuitry to compare a current through the inductor with a threshold current, and to control one or both of the at least two switches, based at least in part on the comparison; and a second circuitry to randomly vary the threshold current over consecutive cycles of switching of the at least two switches.
