Part Number: UCC28070 Other Parts Discussed in Thread: UCC28064A , Tool/software: Hello expert,
Could UCC28070(CCM) and UCC28064A(CrM) externally apply High VDC input (100Vdc-300Vdc) then Boost to Bulk cap. for working normally?
Its VINAC pin is…
Part Number: UCC28070 Tool/software: Hi Ulrich, I hope this message find you well.
I need your help regarding to the design of 2kW PFC based on UCC28070. The problem regards the Vout regulation during transient load.
The voltage input specifications…
Part Number: UCC28070 Tool/software: Hello, I am working on 500W PFC design using the UCC28070EVM. I recalculated component values using the Set-up Tool SLUC114 Rev 2.0 and applied these changes to the EVM. The boost inductors are MnZn (example Wurth…

Part Number: UCC28070 Other Parts Discussed in Thread: TINA-TI , , Tool/software: I find TINA-TI to be quite outdated and difficult to obtain the full version due to its paywall, which makes it challenging to utilize effectively.
While I can't recall…
Part Number: UCC28070 Tool/software: Dear Ulich,
I hope this message finds you well. I was out of the office for a while and, unfortunately, was unable to attend to this design earlier.
As a reminder, this is based on the 6.6kW wide-input voltage…
