His innovative ideas have not only advanced existing engineering concepts but also opened new avenues for efficiency and functionality in electrical components.

Latest Patents

Maxwell's most recent patents include groundbreaking technologies such as integral molded heat sinks on DC-DC converters and power supplies. This technology features a power supply module with a printed circuit board (PCB) that incorporates various electrical components to transform input voltage into output voltage. A unique aspect of this design is the heat sink, which covers almost the entire surface area of the PCB. This heat sink is constructed from a thermally conductive and electrically insulating polymer compound, such as liquid crystalline polymer or polyphenylene sulfide. By using injection molding, the heat sink is bonded to the PCB, significantly enhancing heat dissipation efficiency.

Another recent patent is a power supply packaging system designed for high current, low voltage applications. This system employs bare die power FETs directly mounted to a thermally conductive substrate, allowing for effective heat dissipation. The close coupling of FETs to the substrate, combined with high interconnect densities and the integration of a magnetic core element, provides a sophisticated solution that allows for the inclusion of transformer windings, either for isolation transformers or inductors.
