Abstract: Techniques are disclosed for providing an adaptive and scalable output drive current by a lighting driver, which helps mitigate issues related to binning of solid state light sources. The disclosed techniques may be implemented, for example, with the use of header pins and one or more jumpers or so-called shunt connectors. This allows for a given driver with a constant current output to provide any number of desired output drive currents on demand, by switching and/or adding and/or removing one or more shunt connectors across the appropriate header pins. The header may include any number of pin-pairs, with each pin-pair capable of receiving a shunt connector. Any number of driver topologies may be implemented with the header, such as flyback, buck, boost, buck-boost, and variants thereof.
