Abstract

A hybrid power converter and a method with low power losses over an extended conversion range are presented. The converter maintains low conversion losses associated with reduced inductor ripples not only for a single conversion ratio, but over a wide range of conversion ratios. The power converter has a ground terminal, an input terminal for receiving an input voltage and an output terminal for providing an output voltage with a target conversion ratio. The power converter has an inductor; a first flying capacitor selectively coupled to the inductor; a second flying capacitor selectively coupled to the inductor; a network of switches; and a driver adapted to operate the converter in a first mode associated with a first range of conversion ratios.
