CURRENT SHARING MISMATCH REDUCTION IN POWER SEMICONDUCTOR DEVICE MODULES
Abstract:
In a general aspect, a power module includes a substrate having first, second and third patterned metal layers disposed on a surface of the substrate. The module also includes a first high-side transistor disposed on the first patterned metal layer, a second high-side transistor disposed on the first patterned metal layer, a first conductive clip electrically coupling the first high-side transistor with the second patterned metal layer, and a second conductive clip electrically coupling the second high-side transistor with the second patterned metal layer. The module further includes a first low-side transistor disposed on the second patterned metal layer, a second low-side transistor disposed on the second patterned metal layer, a third conductive clip electrically coupling the first low-side transistor with the third patterned metal layer, and a fourth conductive clip electrically coupling the second low-side transistor with the third patterned metal layer.
