Abstract: Techniques and systems for electronic circuit board design is provided herein. An example apparatus comprises an input structure that couples an input voltage node on a circuit board to input nodes of more than one voltage regulator circuit, wherein at least controller footprints differ among each of the more than one voltage regulator circuit. The apparatus further comprises a shared structure that couples switch nodes of the more than one voltage regulator circuit to a first terminal of an inductor footprint common to the more than one voltage regulator circuit, and an output structure that couples a second terminal of the inductor footprint to an output voltage node.

Abstract: A printed circuit board is provided. The printed circuit board includes a flexible region. The flexible region includes a first copper layer, a first dielectric layer, a second copper layer, an adhesive layer, and a first metal layer, in the order listed. The first metal layer includes a metal film having a tensile strength greater than the first and second copper layers and greater than the dielectric layer.
