Part Number: UCC28064A Tool/software: Hi,
I want to reset UCC28064A when it latches due to some kind of faults such as CS-open, TSET -open and short operation, open loop, UVLO, external disable, brownout and redundant overvoltage (HVSEN). Although I…
Part Number: UCC28064A Tool/software: Hi E2E When I asked a question before, I was told that the maximum switching frequency was 300kHz, but when I checked the actual device, the maximum frequency was about 370kHz. What is the maximum frequency of the…
Part Number: UCC28064A Tool/software: Hi, I'm looking at the SLUAAD0 application note on how to parallel two UCC28064A PFC controllers. I'm really confused by this part of the document...
The note implies we can adjust the resistive divider in…
Hello,
If the output is loaded and you trigger OCP the FETs will stop switching and the boost capacitor voltage will decrease. That is what is expected.
This function is really for inrush current limiting to protect the FETs. PFC boost design are protected…
Part Number: UCC28064A Tool/software: Hi
We are activating interleaved PFC with "UCC28064A". When I take out the electric current of rated load, the difference between A-phase and B-phase is 180 degrees and the PFC works properly. However, when…
Part Number: UCC28064A HI TI,
I have Current distortion issue with UCC28064A at 85Vac,160W.
Current distortion occurs near peak voltage.
Could you give me some advice on the solution?
