Question 1) What is max bandwidth for the PFC control of the IC UCC28070?
We have RT tuned to 30Khz and 95% duty cycle.
We noticed that when we subject the output to a pulse load, >200A at a period of 800mS, 75% duty cycle, we see occasionally observe the output oscillate due to the PFC control not being able to regulate it.
I could not find anywhere on the data sheet that specifies how to set response for load regulation.
Thank you.
