PCB Layout Precautions

Thermal Copper Area

Pin 5 and 6 of IC need copper to dissipate, which means shopping copper in the bottom layer and the

surface layer is necessary to reduce temperature and improve performance.

The distance between DRAIN pin wiring and transformer should be as short as possible. It is appropriate to

keep small loop area and no big area copper.

FB pin wiring should be away from high-voltage loop with more than 1mm spacing to avoid interference.
