Hi Team,
Our customer simulated the UCC256303 in Webench and before he build the board he would like to ask for your opinion if the design will work.

Additionally, he would like to clarify about the custom parts mentioned in the BOM. It seems that these parts are not readily available from distributors, does he really need an ESR of 1 mΩ? If not, what is the lowest ESR of readily available parts he can use?
