A.
The PowerPAD is electrically isolated from all active circuity and pins. Connection of the PowerPAD to the PCB
ground plane is highly recommended, although not required, as this plane is typically the largest copper plane on a
PCB. The thermal performance will be better with a large copper plane than a small one.
