    Abstract: Monolithic power stage (Pstage) packages and methods for using same are provided that may be implemented to provide lower thermal resistance/enhanced thermal performance, reduced noise, and/or smaller package footprint than conventional monolithic Pstage packages. The conductive pads of the disclosed Pstage packages may be provided with a larger surface area for contacting respective conductive layers of a mated PCB to provide a more effective and increased heat transfer away from a monolithic Pstage package. In one example, the increased heat transfer away from the monolithic Pstage package results in lower monolithic Pstage package operating temperature and increased power output. In another example, a monolithic Pstage package may be provided with an adaptive application-oriented interface and a multi-function pin that allows the same monolithic Pstage package to automatically detect and select between a relatively higher power information handling system application, and a relatively lower power information handling system VR application.

    Abstract: An information handling system includes a power supply configured to provide a main power bus and a secondary power bus and a USB-C port. The USB-C port includes a connector that provides an internal power bus, an input selector that couples the internal power bus to the main power bus, and a controller that enables/disables the coupling of the internal power bus to the main power bus by the input selector, and selectively couple the secondary power bus to the internal power bus. The controller further determines that an over-voltage condition is exhibited on the first internal power bus, and, in response to determining the over-voltage condition, disables the first input selector from coupling the first internal power bus to the main power bus and uncouples the secondary power bus from the first internal power bus.
