I mean PWM on high.
PWM is simply turning on at percentage, e.g 80% duty cycle from the max current you're getting. As the voltage drop, your max also drops, so 80% of your max also drops.
In short, without V or I regulation, you will see consistent drop in current as the voltage drop, whether or not your use PWM.
Given this driver maintains the current throughout 4.2V down to 3.5V, it must have a regulator of some sort.
You don’t get it.
I mean PWM regulation.
Sorry guys for bringing this old theme up. I also have this BIC c8 with 5 modes which started to annoying me… Is there a way to have only one mode (the best brightness)? Can i connect it directly to the LED or it would burn this way? Thanks
