Selamun Aleykom, I am an electronics and telecommunication engineer and I am quite experienced with hardware and embedded systems' deisgn. I have designed many LED lighting projects before and I have used COB leds before too. I have checked your requriements. I can help you with a MOSFET and a microcontroller or a VCO that can produce the PWM signal directly without any microcontroller requirements and then you use a pot to dim the light. I can also troubleshoot your PCB. So just give me all the details and I will do my best to help you. Best regards
