Abstract: Embodiments of the invention include a printed circuit board (PCB) assembly that includes advanced component in cavity (ACC) technology and methods of forming such PCB assemblies. In one embodiment, the PCB assembly may include a PCB that has a cavity formed on a first surface of the PCB. A plurality of contacts may be formed in the cavity. The cavity provides a location where components may be electrically coupled to the PCB. Additionally, a package that is mounted to the PCB may extend over the cavity. Since the package passes directly over the component, the components may be used to electrically couple the package to one or more of the contacts formed in the cavity. Accordingly, embodiments of the invention allow for the surface area used for components to be reduced, and also improves electrical performance of the PCB assembly by positioning the components proximate to the package.

Abstract: Embodiments disclosed herein include two stage voltage regulators for electronic systems. In an embodiment, a voltage regulator comprises a switched capacitor voltage regulator (SCVR). In an embodiment, the SCVR receives a first voltage as an input and outputs a plurality of SCVR output voltages. In an embodiment, the voltage regulator further comprises a low-dropout (LDO) regulator. In an embodiment, the LDO regulator receives one or more of the plurality of SCVR output voltages as LDO input voltages, and where the LDO regulator outputs a second voltage.
