Abstract
A power switching module includes a substrate having at least one silicon die forming at least one power switching element and having leadframe terminal posts extending away therefrom. A planar negative rail layer providing a negative power supply and including a non-inductive current shunt resistor formed therein and a planar positive rail layer providing a positive power supply are positioned at the substrate so that the negative rail layer and the positive rail layer are coplanar with respect to each other. A phase output layer providing a phase output signal is also positioned at the substrate. Each of the layers are electrically isolated from each of the other layers and are electrically connected to the substrate.
