Questions for your ADP2503 datasheet

Dear Sir/Madam,

 

Our customer is designing with your ADP2503 power.

So I got a couple of questions as following.

 

Question-1

What is the supply voltage Vin of Fig-26,27 on your datahseet page9-10?

There are the scope shot of start up time for PWM mode on your datasheet Fig-26,27.

But I cannot find Vin on there.

 

Question-2

What should we think about the min and max time of following 200usec?

(page-11, on your datasheet)

>SOFT START

>When the ADP2503/ADP2504 are started, VOUT is ramped from

>0 V to its final programmed value in 200 μs (typical).

 

Question-3

As for the above 200usec, is this 200usec applied for any input voltage also?

Is the start-up time constant without depent on boost mode or buck mode?

 

Thanks Kaos
