Abstract: The present invention generally provides a case for a printed circuit board which forms a single in-line pin configuration from an edge connected circuit board. The case includes a frame enclosing the edges of the circuit board and a base at a mounting plane side of the frame. Connector pins affixed to the edge connectors of a printed circuit board are secured to the printed circuit board and extend from the base. A tab extending generally parallel to the frame from an edge of the base provides a smooth vacuum pick up engagement surface for handling and placement of the present case.

Abstract: The heat sink is mounted on a back plane of an auxiliary circuit board and the auxiliary circuit board is mounted on a main circuit board. In one embodiment, the heat sink is planer and extends between parallel auxiliary and main circuit boards. A finned heat dissipating member is at one side of the planar portion. Mounting pins in channels mount the heat sink to the main circuit board. The second embodiment is u-shaped and stands on edge to mount the auxiliary circuit board perpendicular to the main circuit boards. Mounting pins in channels of the second embodiment likewise mount the heat sink to the main circuit board.

Abstract: A housing for a toroid coil has side walls closely formed around the coil and a top connected at a gap from the side walls by attachments. The top provides a flat, relatively smooth vacuum pick up surface for mounting the coil on a circuit board and is removable by breaking off the attachments. The side walls have a front wall with wire wrap posts extending therefrom positioned so that the wire of the coil lies in the mounting plane for surface mount connection when wrapped on the posts. Slots are provided in the front wall to receive the wire to prevent cutting or scoring of the wire or its coating or cover during removal of the top. The back of the walls is open to reduce length and thickened supports are provided at the edges of the walls adjacent the back.

Abstract: A power conversion architecture includes one control capable of simultaneous operation with multiple power conversion circuits. The function of the controlling mechanism includes an output signal proportional to one or more inputs to the controlling mechanism for the purpose of maintaining a destination level at a substantially constant value. The function of each power conversion path is to transfer power from a source to a destination in an amount dictated by the controlling mechanism. The function of the parallel power conversion architecture is to proportionally distribute the power transfer between all power conversion paths.

Abstract: The heat sink is mounted on a back plane of an auxiliary circuit board and the auxiliary circuit board is mounted on a main circuit board. In one embodiment, the heat sink is planer and extends between parallel auxiliary and main circuit boards. A finned heat dissipating member is at one side of the planar portion. Mounting pins in channels mount the heat sink to the main circuit board. The second embodiment is unshaped and stands on edge to mount the auxiliary circuit board perpendicular to the main circuit boards. Mounting pins in channels of the second embodiment likewise mount the heat sink to the main circuit board.

Abstract: The present invention provides a housing for an auxiliary circuit to be connected to a main circuit. The housing includes a heat tab for conducting the heat away from the auxiliary circuit components and an insulating case which is molded together with the heat tab to interlock the heat tab to the case. The case is molded around a chamfered edge of the heat tab. The insulating case includes a back and two sides extending from the back to define an area which contains the auxiliary circuit components. The heat tab is molded into the back and faces the component area so heat generated from the components can be spread to the main circuit by the heat tab. Openings may be provided through the back of the insulating case. The heat tab and legs on the sides of the housing are used to mount the power supply to a circuit board.

Abstract: A holder for a toroid coil has a planar top surface for engagement by a vacuum pickup and four side walls extending to a mounting plane and defining a toroid containing space therewithin. Wire wrap posts extend from one side of the holder and wire pass through openings enable the wire to hold the coil in place while permitting the solder connection location to lie outside the holder in view for inspection.
