Abstract

The present invention is a printed circuit board design having a configurable voltage supply and a method for implementing a configurable voltage supply PCB with a family of circuit designs. The printed circuit board is designed such that voltage supply planes can be configured to match the device requirements for different ICs inserted into the PCB. The PCB comprises electrically isolated conductive layers that are split into a plurality of electrically isolated fixed and undefined voltage planes. The fixed voltage planes are each coupled to a different supply voltage provided by an external power supply. Undefined voltage planes are coupled to fixed voltage planes with insertable conductive jumpers to obtain the desired voltage supply for each voltage plane. The voltage plane configuration of a particular PCB can be changed depending on where jumpers are inserted to accommodate device voltage requirements over a family of devices.
