If it's for one of the common chips, most over current, over voltage, and thermal protections are built right into the chip itself.

For a discrete design we would need to see your schemetic.

Hello dear friend,
please consider to rename your company.

"pcba2z problems" should fit much better if you need us to find "solutions".

Do you point your customers to this forum if they run into trouble with your products? How can you give support for products you sell, but don´t even understand?

From what I've seen so far it looks a lot more like your main activity is ripping off hobbyists.

What was the plan... get our schematic, make a board and sell it as your own design?
