Publish a LED power supply with 220V input, maximum voltage 28V, and maximum current 3A. (Schematic diagram, circuit board)

Some of the device parameters on the schematic diagram are not very accurate, so please pay attention to this. Someone once produced this power supply in small batches at a cost of 25 yuan.
