Programmable Current, Constant Current LED Drivers

A programmable constant current LED driver is an electronic device that provides a constant and regulated current to drive one or multiple light emitting diodes (LEDs). The "programmable" aspect refers to the ability of the driver to adjust the current output, either through a digital interface or analog control inputs.

This type of LED driver is used to ensure consistent performance of the LED lighting system over time and across different operating conditions, such as changes in temperature or voltage. By regulating the current, the LED driver helps to maintain a stable light output, avoid over-driving the LED, and extend its lifespan.
