Part Number: TPS54540-Q1

Dear support member,

I have a question.

My customer used TPS54540-Q1.
Currently in mass production.

There was a phenomenon that the duty of the switching voltage waveform changes.

There is a question as to whether the phenomenon of changing duty cycle is related to the waste time before switching inside the IC works.

Question1
Does the IC have a the waste time before switching responds?

Question2
Is waste time related to changes in the Duty cycle?

Best regard.
Bob Lee.

I am not sure I fully understand the question.

If you can send your schematic and some 'scope plots of the phenomenon,

then we may be able to help answer your question more effectively.
