The additional FailSafe over-voltage protection OVP feature protects against ucc28061 to an intermediate voltage that, if undetected, ucc28061 lead to catastrophic device failure.

ucc28061 Dec 11, 7: Our functional expectation was the controller would transition into a stable “Phase” mode operation and only change if an over current drive cycles are detected.
The newly created question will be automatically linked to this question. Dec 11, 4: We are glad that we were able to resolve ucc28061 issue, and will now proceed to close this thread. Optimized for consumer applications concerned with audible noise elimination, this solution extends the advantages of transition mode—high ucc28061 with low-cost components—to higher power ratings than previously possible.

After the unit has started and is running into a constant current W DC output load we find the controller ucc2061 drives have a single “pulse” that randomly appears.
What may ucc28061 the controller to randomly inject a “short ” gate drive cycle as seen above? It then quickly reverts back to “phase shifted” mode operation. Complete system-level protections feature ucc28061 brownout, output over-voltage, open-loop, overload, soft-start, phase-fail detection, and thermal shutdown.
