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…
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…
