Abstract
A variable power device circuit includes a plurality of devices for driving a load. Each of the devices has a body, which is electrically isolated from the substrate. All of the devices are coupled to an output node. The load is also coupled to the output node. A controller selectively turns on individual or multiple ones of the devices based on the electrical requirements of the load.
