Abstract: A cascaded configuration of regulator circuits can be co-integrated within a commonly-shared integrated circuit package (such as an integrated electronic module). Such co-integration can include placing a switched-mode regulator circuit in close proximity to a linear regulator circuit. Magnetic field coupling between the regulator circuits is generally a non-linear function of a separation between the circuits. The switched-mode regulator circuit can generate noise that may adversely impact the linear regulator output. Magnetic coupling between the regulator circuits within the module package can be suppressed or eliminated using a magnetic barrier. The barrier can be magnetically permeable and electrically non-conductive.

Abstract: An integrated circuit package may include a semiconductor die, a heat spreader, and encapsulation material. The semiconductor die may contain an electronic circuit and exposed electrical connections to the electronic circuit. The heat spreader may be thermally-conductive and may have a first outer surface and a second outer surface substantially parallel to the first outer surface. The first outer surface may be affixed to all portions of a silicon side of the semiconductor die in a thermally-conductive manner. The encapsulation material may be non-electrically conductive and may completely encapsulate the semiconductor die and the heat spreader, except for the second surface of the heat spreader. The second surface of the heat spreader may be solderable and may form part of an exterior surface of the integrated circuit package.

Abstract: System and methodology for controlling output current of switching circuitry having an input circuit and an output circuit electrically isolated from each other. A value of the output current may be determined based on input voltage, input current and reflected output voltage representing the voltage in the input circuit which corresponds to the output voltage. A switching element in the input circuit is controlled to produce the determined value of output current.
