Hello,

I am trying to understand the design of the UCC28C56EVM board.

I see that they are using the flyback transformer ZD2200-BE from Coilcraft. This transformer was design to only handle up to 20W.

The UCC28C56EVM board is supposed to work up to 40W. Is there any reason why this transformer was selected?

I would appreciate any help

Hi,

The transformer on the EVM is ok to handle 40W. You can obtain the EVM to test to check.

Hello,

I have the EVM but I am trying to understand the design as there is no design calculator for this specific EVM online. I saw that on their website and I contacted them and they say "While the UCC28C56EVM test board says it can handle up to 40W power, our ZD2200-BE Flyback Transformer was designed to only handle up to 20W power. We have not developed a similar transformer for 40W capability."

Hi,

You can test the EVM to get 40W on this EVM. If you see problems from your test please let us know.
