UCC28704: UCC28704

Part Number: UCC28704

Hello,
I have designed this UCC28704 AC/DC flyback converter circuit. I am wondering if the return path of the bridge rectifier is correct?. Also, can you help me find a compliant PN for a transformer to be used with the Converter IC?
Thanks,

Hi Ahmed,

Thank you for the query on UCC28704.

I think bridge rectifier is good. Please refer another reference design similar to this:

I am sorry we can help with transformer selection. I would request you please contact Wurth electronics/ coilcraft to get custom transformer built for this application.

Please refer links below there are some designs which use tranformer for this IC. If you are lucky there could be something ready here:
