Abstract
A driver circuit for a Light Emitting Diode (LED) is disclosed. The driver circuit is capable of supporting a constant LED current circuit configuration as well as an external resistor-controlled LED current circuit configuration. By integrating both configurations into a single driver circuit, the either circuit configuration can be selected without requiring a different driver circuit.
