TPS2500: Boost operation at loosely regulated 5Vin?

Allen Wachter
Expert 6720 points
Part Number: TPS2500

How will the boost perform if the input voltage is a nominal 5V +10/-18%?  What is the expected output voltage range?  Will the output through the USB switch be within the +/-10% tolerance of the USB spec?

Thanks!

    Hi, Allen,

    I will try to find some test data and reply you then.

    Hi, Allen,

    I can't find the test data, do you need me to do some test? If yes, it will take 1-2 weeks, because I need to apply for EVM.

    Regards,

    Hi Bob,

    I think this would be good information to have so I am willing to wait 1 -2 weeks for the data.  

    Thanks!

    Hi, Allen,

    Sorry for late reply. I just got EVM this week, hope it's not too late. Please see the test result as below. Output voltage is not out of range from the test result.
