ABSTRACT:
The present invention is a printed circuit board having conductive layers split into electrically isolated voltage supply plane regions each plane region being connectable to an external supply voltage. The voltage supply plane regions are split to reduce the total number of PCB conductive layers. Voltage supply plane regions are configured to match the device voltage requirements and their placement on the PCB. In the case in which a circuit includes a device having two voltage supply requirements, a first set of the device's power supply pins are fixedly coupled to a first voltage supply plane region and a second set of the device's power supply pins are fixedly coupled to a second voltage supply plane region. In this instance, each of the first and second voltage supply plane regions are fixedly connectable to external voltage supplies or to a voltage regulator according to the voltage supply requirements of the device.
