If you have further questions related to this thread, you may ucc28061 “Ask a related question” below. The circuit has been running in a “phase” mode and then appears to change over to a “synchronous” mode for a single cycle. Ask a new question Ask a new question Cancel. This approach delivers inherently strong matching, faster ucc28061, and ensures ucc28061 each channel operates in transition mode.

Hi John, thanks for your post. Ucc28061 newly created question will be automatically linked to this question. Ucc28061 of the over current detection fault is there another ucc28061 for it to transition in and out of the “phase” mode?

Our functional expectation was the controller would transition into a stable “Phase” mode ucc28061 and only change if an over current drive ucc28061 are detected. It then quickly reverts back to “phase ucc28016 ucc28061 operation. Ask a related question What is a related question?

Optimized for consumer applications concerned ucc8061 audible noise elimination, this solution extends the advantages of transition mode—high efficiency with low-cost components—to higher power ratings than previously possible. Operating Supply Max V. No license, either express or implied, by estoppel or otherwise, is granted by TI. After the unit has started and is running into a constant current W DC output load we find the controller gate drives have a ucc28061 “pulse” that randomly appears.

What may cause the ucc28061 to randomly inject a “short ” gate drive cycle as seen above? The additional FailSafe over-voltage protection OVP cuc28061 protects against shorts to an intermediate voltage that, if undetected, could ucc28061 to ucc28061 device failure.

Ucc2801 Optimized for consumer applications concerned with audible noise elimination, this solution extends the advantages of transition mode—high efficiency with ucc28061 components—to higher power ratings than previously possible. The following drive cycle you see it has transitioned back in to a “phased ” gate drive sequence. The load is fixed and the AC input line is set at Vac.
