  • Publication number: 20150331438
    Abstract: A complete power management system implemented in a single surface mount package. The system may be drawn to a DC to DC converter system and includes, in a leadless surface mount package, a driver/controller, a MOSFET transistor, passive components (e.g., inductor, capacitor, resistor), and optionally a diode. The MOSFET transistor may be replaced with an insulated gate bipolar transistor, IGBT in various embodiments. The system may also be a power management system, a smart power module or a motion control system. The passive components may be connected between the leadframe connections. The active components may be coupled to the leadframe using metal clip bonding techniques. In one embodiment, an exposed metal bottom may act as an effective heat sink.

  • Patent number: 8586419
    Abstract: The present technology is directed toward semiconductors packaged by electrically coupling a plurality of die to an upper and lower lead frame. The opposite edges of each corresponding set of leads in the upper lead frame are bent. The leads in the upper lead frame are electrically coupled between respective contacts on respective die and respective lower portion of the leads in the lower lead frame. The bent opposite edges of each corresponding set of leads of the upper lead frame support the upper lead frame before encapsulation, for achieving a desired position of the plurality of die between the leads of the upper and lower lead frames in the packaged semiconductor. After the encapsulated die are separated, the upper leads have an L-shape and electrically couple die contacts on upper side of the die to leads on the lower side of the die so that the package contacts are on the same side of the semiconductor package.
