Ducky Shine 2 PWM Noise
Posted: 13 Aug 2014, 14:30
Hi Folks,
my Ducky produces a very high quiet sound if the backlight gets full powerd. with every stage of dimming it down, it becomes less noisy. is this a result of PWM-Dimming? any ideas how to fix it?
Here are some Pics from my PCB and the Location where this Sound comes from. Could it be the Clock Generator?
