First example on page 4 shows how to implement dimming with only a potentiometer. No 555/PWM source needed.here is the datasheet
http://www.xppower.com/pdfs/SF_LDU08-48.pdf
should have gone with a meanwell LDD driver half the price and higher PWM amplitude.
Did you purchase the controller already? If not take a look at the pt4115 chip. Very easy to use and it has a DIM pin where you can apply PWM.hi thatoneguy Thats not going to teach me much i want to build the pwm and learn something .
I apologize for trying to be helpful based on your self-professed knowledge of electronics in the OP:hi thatoneguy Thats not going to teach me much i want to build the pwm and learn something .
can anyone help me out here with a schmatic i am a nooby to electronics
