A pre-packaged chip includes a chip having at least one electrical top contact at a top side of the chip and at least one electrical bottom contact at a bottom side, a first laminate layer on the top side, a second laminate layer on the bottom side, the first laminate layer and the second laminate layer being laminated together to sandwich the chip therebetween, a first metal layer on the first laminate layer and electrically contacted to the at least one electrical top contact via at least one top contact hole through the first laminate layer, and a second metal layer on the second laminate layer and electrically contacted to the at least one electrical bottom contact via at least one bottom contact hole through the second laminate layer. The pre-packaged chip is free from any contact hole extending from the first metal layer to the second metal layer.

A multi-level converter comprises one or more flying capacitors configured to operate at balanced voltages. The multi-level converter comprises a plurality of switching groups comprising pairs of switches operable to transfer energy to and from an inductor and the one or more flying capacitors for inverting an input voltage to an inverted output voltage. The multi-level converter comprises the inductor configured to operate according to an inductor frequency greater than a switching frequency used to control the plurality of switching groups.

Multi-level inverting buck-boost converter architecture

According to some embodiments, an apparatus comprises a multi-level power converter configured to convert an input voltage to an output voltage, wherein the multi-level power converter comprises one or more switching groups, wherein a switching group of the one or more switching groups comprises a pair of switches and a flying capacitor, and a controller configured to determine a duty reference for the switching group, determine a duty correction factor for the switching group based upon a flying capacitor voltage error of the flying capacitor, determine a sign correction signal based on a flying capacitor ripple voltage, and determine a duty command for activating the pair of switches based on the duty reference, the duty correction factor, and the sign correction signal.
