I have a doubt and I'm facing an issue too,
1. when we designing a PCB for flyback LED driver, is there any problem if the MOSFET drain pin and transformer pin distance is about 16mm? I made it like that because I need to accommodate the heat sink!
2. Current sensing Resistor: If the wattage of the current sensing resistor is above the the rated wattage is there any problem? Can I use a single 0.22R 2W resistor instead of 6x1206 chip resistor?
3. I would like to know Ground of the Rcs should be an independent path and how much thickness it has to be needed!?
4. What happens if the snubber circuit is a bit away from the drain pin?
I would be grateful if someone could clear my doubt and help me to improvise the design or to resolve the issues by solutions
Thanks in Advance
