UCC28810: (SLUA752–August 2015) Isolated 70-W Streetlight LED Driver Using UCC28810 Application Report Transformer T1

Part Number: UCC28810

Dear Team,

Are you able to provide any information about transformer T1 in this application report?

https://www.ti.com/lit/an/slua752/slua752.pdf?ts=1638288981432&ref_url=https%253A%252F%252Fwww.google.com%252F 

Has it been used in an EVM? 

Are you able to provide enough details about its construction so that my customer's supplier can manufacture it?

Thank you,

Daniel Waleniak

    Hi Daniel,

    I've reached out to the authors of the app note to see if they can help us.  This may take another day to get a response.

    Has your customer considered one of the reference designs?  There's more info on the transformers in those files.

    Hi Daniel,

    I wish I could help more, but unfortunately, I am unable to locate the specific information on the transformer used in this app note. 

    My suggestion would be to follow their inductor design procedure (albeit rather abbreviated), along with the much more detailed transformer design from the app note they reference at the end of the paper, http://www.ti.com/product/tps92314 . It is likely the procedure they followed in their design of T1.

    Regards,

    Ray

    Hello Ray,

    Sorry for my late response, but I do appreciate you getting back to me. If anything changes please feel free to reach me. In the meantime I will ask the customer to study the document and designs using it.

    Regards,

    Daniel
