Abstract
A switching converter comprising: a first switch having a first terminal adapted to be coupled to a first DC voltage, an inductor having a first terminal coupled to a second terminal of the first switch; the inductor having a tap and a second terminal; the second terminal coupled to a capacitor, the capacitor adapted to have a second DC voltage thereon; and a second switch having a first terminal coupled to the tap of the inductor and a second terminal coupled to a common line coupling said first and second DC voltages.
