Systems and methods for driving light-emitting diodes |
摘要 |
At least some embodiments include a LED driver system. The system includes multiple branches of series-coupled LEDs, multiple current sources, and control logic. Each of the current sources is coupled to a separate branch of series-coupled LEDs. The control logic is coupled to the current sources, and is configured to regulate current through each branch based at least in part on a feedback voltage measured at a node in one of the branches. |
