Hello,
My customer has aquestion about TP61181A.
Could you teach me about question.
It is written in IFB Pin Unused of data sheet, and the GND connection or open.
However, the level of the output in Vo due to the difference in treatment of unused pins are different.
<Open>
During the start-up, Vo rises to over voltage threshold.
And, IC After detecting the Zero Current, I exit the feedback loop.
<GND connection>
Vo is not increased to over voltage threshold, it is Regulation Voltage after startup.
[Question 1]
When not in use of IFB,How does this affect IC operation in open and short.
[Question 2]
When you open the processing [IFB PIN],How do Vo happens if exits the Feedback loop?
Regards,
T Kishi
