Abstract
A technique for extending the size of a power transistor beyond one integrated circuit. In one embodiment, a method of extending the size of a power transistor beyond one integrated circuit includes a master integrated circuit comprising a master control circuit, master driver circuit and master semiconductor switch and one or more slave integrated circuits comprising a slave semiconductor switch and a slave driver circuit. In one embodiment the master semiconductor switch terminals are coupled to the corresponding slave semiconductor switch terminals. In one embodiment the master driver circuit input and slave driver circuit inputs are coupled to be driven by a control signal being the output of the master control circuit.
