Abstract: A fully integrated 3-level DC/DC converter merges characteristics of both inductor-based buck converters and switched-capacitor converters. The 3-level converter uses both a flying capacitor and an output inductor and operates with a four step cycle. During two steps of the four step cycle the capacitor regulates the output voltage and during the remaining two steps, the inductor regulates the output voltage. The combination of the capacitor and inductor allows the 3-level converter to efficiently regulate the output voltage across a wide range of levels and load currents. A power supply and an integrated power distribution system using the DC/DC converter are also disclosed.
