Abstract
A power efficient device for driving a load comprising a low current path and a high current path, wherein the high current path is driven by a first voltage source. In order to accommodate larger turn on voltages of possible load devices while maintaining low power operation, an additional voltage source exceeding the voltage source in the high current path is introduced in the low current path.
