Hello,

what is the difference between UC3854DWTR and UC3854DWTR-F, I couldn't find the meaning of the suffix '-F'.

Thank you,

Hi Robert,

Where are you seeing the -F option? Here are the orderable options on ti.com:

UC3854

I hope this helps.

Hi Robert

I found the difference, the UCC3854 has an Argon Plasma clean as part of the manufacturing process, the UCC3854-F does not. This is the only difference I could find.

I hope this answers your question.
