Abstract
A programmable LED constant current driver circuit for driving LEDs at constant current and dimming the LEDs using standard, off-the-shelf dimmers is provided. The current driver circuit of the present disclosure includes a temperature compensation feature which controls the on time for the LEDs based on a measured temperature of the current driver and associated circuits. In another embodiment, the current driver circuit is designed to receive a 24 VAC input and drive one or more LEDs in a transformer-based system dimming system.
