TPS63060 – About PG and Soft Start function

Guru 21045 points
Other Parts Discussed in Thread: TPS63060

Hi Team,

 

Our customer is studying about PG and soft start function.

Please let me ask the following question.

 

------

[Q1]

We would like to know the timing when the PG output is changed from "Low" to "High".

Does the PG output change after the output voltage reached the target output voltage?

If yes, please let me know this delay time at all conditions.

------

 

[Q2]

I’m understanding that The device ramps up the output voltage in a controlled manner even if a large capacitor is connected at the output.

So, I believe that in same condition(Vin, Vout , Iout), the rise time of output voltage are changed by the output capacitor value.

Is my understanding correct?

And, Please let me know if there is other factor that the rise time of output voltage is changed.

------
