Abstract: Methods, and systems, are presented for a Structural Bridge for Electrically Isolated Metal Clips by mounting on a substrate a first and a second circuit. These first and second circuits can include Component on Package (CoP) electronic parts that are electrically contacted to the substrate with metal clips mounted on the surface of the substrate. The metal clips are electrically connected to respective circuit first and second circuits by an electrical connection on or in the substrate. The metal clips are folded over the respective first and second circuits. The folded-over portion of the first metal clip and the folded-over portion of the second metal clip are electrically isolated from each other. A third circuit package that is mounted on and electrically connected to a folded-over portion of the first metal clip and to a folded-over portion of the second metal clip.

Abstract: An electronic device and a method of forming such an electronic device are disclosed. The electronic device can include an integrated device package and a component. The integrated device package includes a substrate and a package body over the substrate, and a hole formed through the package body to expose a conductive pad of the substrate. The component is mounted over the package body, and includes a component body and a lead extending from the component body through the hole. The lead includes an insulated portion and a distal exposed portion, and the insulated portion includes a conductor and an insulating layer disposed about the conductor, wherein the distal exposed portion is uncovered by the insulating layer such that the conductor is exposed at the distal portion. The electronic device can also include a conductive material that electrically connects the distal exposed portion to the conductive pad of the substrate.

Abstract: A low-profile coupled inductor is disclosed to provide compact and high performance magnetic coupling. The low-profile coupled inductor has an asymmetrical geometry, having a pair of complementary ferrite cores supporting a pair of conducting strips in an alternating serpentine pattern. One or more core gaps exist between the cores to create a strong flux coupling between adjacent magnetic fields of either conducting strip. The alternating serpentine conductors and core gaps serve to increase energy transfer between the magnetic fields and improve the overall power density of the low-profile coupled inductor.

Abstract: A packaging technology in which power switching elements, such as field-effect transistors (FETs), can be oriented in a vertical position relative to the printed circuit board (PCB) on which the product is mounted. The power die including the switching element(s) can essentially stand “on end” so that they take up very little PCB area. Multiple dies can be positioned this way, and the dies can be attached to a heat sink structure, which is designed to take the heat generated by the dies onto the top of the package. The heat sink structure can be attached to a structure to route the power and analog signals properly to the desired pins/leads/balls of the finished product. Using these techniques can result in a significant increase in the power density (both PCB space and solution volume) of power switching elements, e.g., FETs.

Abstract: This disclosure describes techniques to provide a regulator circuit using a component-on-top (CoP) package. The CoP package comprising a system-in-package (SIP) comprising regulator circuitry, the SIP having a top portion and a first side portion; and an inductor on the top portion of the SIP, wherein: the inductor is coupled to the regulator circuitry via the top portion of the SIP; and a first end of the inductor extends beyond the first side portion of the SIP.

Abstract: A component-on-package circuit may include a component for an electrical circuit and a circuit module attached to the component. The circuit module may have circuitry and at least one leadframe which connects the circuitry to the component both electrically and thermally. The leadframe may have a high degree of both electrical and thermal conductivity and a non-planar shape that provides spring-like cushioning of force applied to the component in the direction of the circuit module.
