The driver accepts PWM dimming but needs a voltage range of ~2-8V, and the PWM controller outputs 7-12V when powered by the 12V input I'll be using.
Is there an easy way I can modify the controller to get the voltage down to this range?
Would lowering the input voltage lower the output range too? Or could I simply change the value of the pot/add in a resistor or two, or would that destroy the PWM signal?
I will be repositioning the potentiometer from the controller as space is very limited in my use case, so some soldering is required anyway. However the theory on this is a bit beyond my skill level.
Many thanks for any help on this
