Power converter assembly with vertically arranged passive components

A method of manufacturing a stacked power converter assembly, the method comprising:

• providing a bottom substrate, a plurality of passive components, and at least one routing substrate;
• arranging the at least one routing substrate and the plurality of passive components on the bottom substrate;
• providing a top substrate;
• arranging the top substrate on the plurality of passive components and the at least one routing substrate, thereby providing a passive sub-assembly;
• providing an active sub-assembly comprising at least one integrated circuit;
• arranging the active sub-assembly on the top substrate, thereby providing the stacked power converter assembly;
• and
• wherein the at least one routing substrate is configured to provide a vertical connection between the top and the bottom substrates, and wherein the at least one routing substrate comprises at least one routing through-substrate via, wherein the at least one routing through-substrate via is configured to provide the vertical connection between the plurality of substrates.
