Arrangement with an integrated circuit mounted on a bearing means and a power supply module arrangement
View Patent ↗A power supply module arrangement with an integrated circuit mounted on a bearing unit and a power supply includes an integrated circuit mounted on a bearing unit and a power supply module arrangement that is placed on the combination of bearing unit and integrated circuit. The power supply module arrangement includes a base extending at least partially over the base of the integrated circuit and/or all around the base of the integrated circuit. The power supply module arrangement allows for greater permissible load jumps, greater permissible current change rates and ever tighter tolerances regarding the constancy of the supply voltage.
1. An arrangement with an integrated circuit mounted on a bearing means and a power supply module arrangement, placed on the combination of bearing means and integrated circuit and whose base at least partially extends over the base of the integrated circuit and/or all around the base of the integrated circuit,
wherein the bearing means has power supply contact points in the area next to the integrated circuit, which are connected to external power supply terminals of the integrated circuit and in that power supply output filter capacitors of the power supply module arrangement are arranged to make electrical connections with the power supply contact points between a substrate of the power supply module arrangement and the power supply contact points, the power supply output filter capacitors being situated between the bearing means and the substrate,
wherein the connection between the external power supply terminals of the integrated circuit and the power supply contact points of the bearing means is made by electrically highly conductive layers of the bearing means which are separated from one another by insulating material.
2. An arrangement as claimed in claim 1 , wherein the insulating material is dielectric material, in particular ceramic material.
3. An arrangement as claimed in claim 1 , wherein the integrated circuit has external power supply terminals on its surface side turned away from the bearing means and in the external power supply terminals lie opposite corresponding power supply output terminals of the power supply module arrangement.
4. An arrangement as claimed in claim 1 , wherein the power supply module arrangement has recesses in the area above the integrated circuit through which to pass projecting parts of a cooling device.
5. An arrangement as claimed in claim 1 , wherein the power supply module arrangement has at least one component-mounting substrate area, which is angled to that surface side of the bearing means on which the integrated circuit is placed.
6. An arrangement as claimed in claim 5 , wherein the angled substrate area, in particular angled approximately at right angles, supports power supply components and rests against a cooling device used for cooling the integrated circuit.
