Selectable output current enables the A6211 to drive many different LED technologies. For a smaller footprint, such as a 1A, 12V, MR16 track light bulb, the A6211 is reconfigured. The reduction in component size enables the A6211 to compete in compact applications. The diagram shows the smaller diode and inductor used for a 1A application on the right as compared to a 3A application on the left.
