You could begin by looking at the UCC28810 EVM-003.  It's a 110-W offline AC-to-DC LED current driver with power factor correction. This design utilizes a three stage approach with a universal input boost PFC stage, a low-side buck stage providing a controlled current source and a half-bridge DC transformer stage to provide isolation to four LED strings.

Here are the Gerbers for the EVM.  Enjoy!

Hi Lisa,

I am also designing a circuit using UCC28810EVM-03. Can you please provide the complete schematic & PCB files of the circuit?

Thank you,

Karan

I think I need to do this in 2 replies...first the schematic....

Hi Lisa,

Thank you very much for your prompt reply & files!!.

Can you also provide PCB files in Altium/ORCAD/Eagle format? (or whatever schematic program you use).

Hi Lisa,

Could you please provide datasheets for the following magnetics used in the EVM Module. These are not available on internet.

Thanks.

Karan

An alternate device for the CTX16-18610 is listed as p/n 750311699 from Wurth Midcom

An alternate device for the CTX33-18441 is listed as p/n 750311697 from Wurth Midcom

An alternate device for the CTX16-18625 is listed as p/n 750311698 also from Wurth Midcom

I am still trying to locate the 18610 for you...

Thank you for the excellent support Lisa!

Could you also suggest any alternative Magnetics  for the following used in EVM Module?

Also if you are able to locate the 18610 datasheet it would be great.

Thank you very much for your prompt support.
