Today I received several of my LED2000DR based LED boards. Everything worked flawlessly when using the chip as a plain LED driver. However, after trying to feed a PWM signal into the DIM pin the dimming worked for about a second but then the board we...

I have adjusted the output capacitors value to 1uF and that seems to have done the trick. I still do not understand why it would destroy an IC with a simple increase of capacitance, considering that this is mentioned in the datasheet:As soon as the d...

Thank you for the information, I indeed read both of those point, however I am just a bit perplexed that the failure mode of having a slightly larger capacitance than expected is the complete destruction of the IC. Since as far as I understand the on...
