Hi, I have a very basic project of dimming 12V led with PWM. We can find some circuit in the market but it is big. I want to make a smaller version of the PCB with UFL connectors. The design should be made in EASYEDA so the SMD components can be attached and shipped. Technical information 1. 10K potentiometer with on-off switch feature. 2. the circuit should not be more than 2cm x 2cm. It can have a dual PCB for added components. 3. PWM frequency should be high so the flickering is not there. 4. when turned ON minimum V should be 7V and the max should be 12V. 5. Input is 12V 5A, the output is 7V -12V 300mA to 3A.
