I received an UCC28730EVM-552, and it runs well.
I'm trying to design a AC/DC(5V,2A). I will use this EVM circuit as reference.
But, My AC Input has 3 lines. (L, N, FG). This EVM can connect only L and N.
I want to connect an AC input FG to this EVM. Such as following diagram
I'm poor at AC power circuit.
If you have any idea, please let me know.
