Abstract
A multi-phase buck DC converter comprise a plurality of storage inductors, a plurality of low-side switches, a first input capacitor, a second input capacitor, a plurality of high-side switches and at least one clamping capacitor. The storage inductors are used to drive a load. The low-side switches are connected to the storage inductors; respectively. The second input capacitor is connected to the first input capacitor in series. The contact of the first input capacitor and the second input capacitor is connected to one storage inductor. A part of the high-side switches are connected in series. One end of each clamping capacitor is connected to any two high-side switches connected in series and the other end is connected to the storage inductors.
