HVLED815PFTR-based LED Driver minimun load

Question asked by cobreces.alvaro on Mar 3, 2014

I am involved in the design of a LED driver based on the HVLED815 IC. It works great with a load greater than 4W, but LEDs start blinking if the load is less than 3W (approx). So, my question is if there is any minimun load required to get a constant current output, or if it is just a dimensioning problem.

Any commnet will be appreciate. Thanks in advance.
Best regards,
