Part Number: UCC2817 Tool/software: hi TI engineers
What are major difference between UCC2817ADR and UCC2817D?
We are using UCC2817ADR in a PFC design.
Thanks
Part Number: UCC2817A Hi,
I have designed the PFC stage using UCC3817AD and want to replace it with UCC2817AD as the ambient temperature around the IC is more than 70C. Have already completed all the design evaluation and testing and is ready for…
Other Parts Discussed in Thread: UCC2817 , UCC2817A , UCC3817A Hi,
What is difference of UCC2817 and UCC2817A?
I saw the following thread, is the reason same?

Hi Yaita-san,
My colleagues Michael O'Loughlin and John Bottrill have written an excellent article on how to design the UCC2817A with a current transformer.
The paper is located here:

Hello David,
I think you are asking for a pfc type power supply that can operate from a rectified 3 phase source. Is that correct? There must be some more design requirements such as power levels,efficiency,power factor, cost .... etc etc. Do you know…
Hello Mason,
Normally for a 3 phase 208V line to line supply, the AC input is first rectified with a 6 diode bridge rectifier.
This provides a mostly DC high voltage with some ripple at 6 times the AC line frequency.
The UCC28070 quantized multiplier…
Hi,
We do not have a reference design available for a three phase pfc stage based on the UCC28180. so I can't say for sure.
The UCC2817 and UCC2854 family of pfc controllers have been used for many years in products that rectify the three phase supply…
