Abstract:
A sequential linear LED driver circuit is provided. The sequential linear LED driver circuit may include a plurality of current sinks, wherein each of the plurality of current sinks is configured to be coupled to a segment of a string of light-emitting diodes (LEDs), and a voltage divider that generates a plurality of reference voltages, wherein each of the plurality of reference voltages is applied to a respective current sink of the plurality of current sinks. The output of each current sink of the plurality of current sinks may be connected at a summing node.
