Constant Current Supply for High Power LEDs - A high efficiency constant current supply based on a switching regulator.

High power LEDs require large currents to operate. Limiting the drive current can be done in several ways but efficiency needs to be considered. The ideal method for driving these LEDs is with a constant current source specific to their needs. A linear constant current source can waste a lot of power and get very hot doing it. A switching regulator would be an ideal choice.

Here is a circuit that uses a switching regulator to make up a constant current supply with efficiency and stays cool....
