Patent ID: 7683553

Claim:
A method of controlling currents in a plurality of loads comprising: receiving a first input voltage on a first pin of an integrated circuit; generating a first regulated voltage on a second pin of the integrated circuit based on the first input voltage, wherein the regulated voltage is coupled to a first terminal of a first load and a plurality of first terminals of a plurality of second loads, wherein the first load has a second terminal coupled to a third pin of the integrated circuit, and wherein a first feedback current is generated in the first load; receiving the first feedback current on the third pin of the integrated circuit; generating an output current on a fourth pin of the integrated circuit based on the first feedback current, wherein the output current on the fourth pin is coupled to gate terminals of a plurality of transistors, and wherein drain terminals of the plurality of transistors are coupled to second terminals of said second loads; and generating a load current in each of said plurality of second loads, but not the first load, using the output current.
