  • Publication number: 20200266159
    Abstract: An embodiment of a circuit includes a circuit module and an inductor disposed over and electrically coupled to the module. Disposing the inductor over the module may reduce the area occupied by the circuit as compared to a circuit where the inductor is disposed adjacent to the module, or to a circuit where the inductor is disposed in the module adjacent to other components of the module. Furthermore, disposing the inductor outside of the module may allow one to install or replace the inductor.

  • Patent number: 9723766
    Abstract: An embodiment of a power-supply module includes a package having sides, a first power-supply component disposed in the package, and an electromagnetic-interference (EMI) shield disposed adjacent to two sides of the package. For example, such a module may include component-mounting platforms (e.g., a lead frame or printed circuit board) on the top and bottom sides of the module, and these platforms may provide a level of EMI shielding specified for a particular application. Consequently, such a module may provide better EMI shielding than modules with shielding along only one side (e.g., the bottom) of the module. Moreover, if the module components are mounted to, or otherwise thermally coupled to, the shielding platforms, then the module may provide multi-side cooling of the components.

  • Patent number: 8951847
    Abstract: Embodiments of a leadframe for a device packaging are used not only for structural support and connectivity to the I/O pins to the external world, but also for housing and/or mounting devices above and below the leadframe. Being electrically conductive, the leadframe also serves as a low resistance interconnect and good current carrier between the bondpads on one device or between the bondpads on different devices above and/or below the leadframe.

  • Patent number: 8946875
    Abstract: A packaged semiconductor device includes at least first and second lead-fingers. A molded structure forms a cavity and is molded around portions of each of the first and second lead-fingers to thereby mechanically attach each of the first and second lead-fingers to the molded structure. A semiconductor structure (e.g., a IC, chip or die) is attached within the cavity. First and second bond wires respectively providing electrical connections between the semiconductor structure and the first and second lead-fingers. A further portion of each of the first and second lead-fingers is mechanically attached to a bottom surface of the semiconductor structure to inhibit relative mechanical motion between the semiconductor structure, the molded structure and the first and second lead-fingers.
