Abstract
A circuit may be configured to deliver current to one or more light emitting diodes (LEDs). The circuit may comprise a first current path configured to deliver a first current to the one or more LEDs, and a second current path in parallel with the first current path, wherein the second current path is configured to deliver a second current through a voltage drop element and to the one or more LEDs. According to this disclosure, a sum of the first current and the second current is regulated based on a sensed current through the circuit.
