摘要:
An electronic multi-output device has a substrate including a first pad, a second pad and a plurality of pins. A first chip with a first transistor has a first terminal on one chip surface and a second and third terminals on the opposite chip surface. The first chip with its first terminal is tied to the first pad. A second chip with a second transistor has a first terminal on one chip surface and a second and third terminals on the opposite chip surface. The second chip with its first terminal is tied to the second pad. The second terminals are connected by a discrete first metal clip and a second metal clip to respective substrate pins. A composite third chip has a third and a fourth transistor integrated so that the first terminals of the transistors are on one chip surface. The second terminals are merged into a common terminal. The patterned third terminals are on the opposite chip surface. The first terminals are vertically attached to the first and second metal clips, respectively. The common terminal is connected by a common clip to a substrate pin.
