Abstract :
This paper describes the design and the implementation of a digital controller for LED driver. By utilizing a simple comparator for sampling the output current a relay base controller has been dimensioned. Using a 5bit DPWM and the relay controller the low frequency limit cycle oscillations can be avoided.
