Hi All,

I have a question about TPS562210A.
The following Power Good is stated as 1.7 times the soft start time.

What is the reason for this 1.7 times?

Hi,

Thank you for your answer.

I understand it was deglitch time. Does 1.7 times make sense?
Customers want to shorten their Power Good time.
That's why I asked.
I think that's possible by adjusting the soft start time.

Hi,

Sure, you can adjust the SS pin cap to short the deglitch time.

Hi,

Are you asking the value why it is 1.7 times , not the other value ?

This data was fixed internally and count the number to define this deglitch time .

Please let me know if i'm not understanging you correctly .

Hi ,

I think it's a system level data, we can define it as other value . Could you let me know your opinion on this ?
