Abstract
In an example embodiment, the controller is designed with a single current sensing circuit that is able to measure the current on multiple LED channels, eliminating the need for each LED channel to have its own current sensing circuit. The current sensing circuit may further be utilized with a control unit, which has an LED control model selection multiplexor (MUX) that switches between real-time closed-loop control and open-loop control.
