Abstract

A DC/DC power converter and a method to convert an input voltage into an output voltage are presented. The power converter may have a first flying capacitor, a second flying capacitor, an inductor, and switching elements. It may control the switching elements such that the switching elements establish a first magnetizing current path from the input node, via the first flying capacitor, via the second flying capacitor, via the inductor, to the output node. The converter may control the switching elements to interrupt said first magnetizing current path after a pre-determined time interval. The converter may control the switching elements such that the switching elements establish a demagnetizing current path from a reference potential via the inductor to the output node. The converter may control the switching elements such that said demagnetizing current path is interrupted when a current through the inductor reaches a pre-determined threshold current value.
