  • Patent number: 11979978
    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.
