TPS63020 / phase margin

Other Parts Discussed in Thread: TPS63020

Hi Team,

Is there any phase margin data using FRA(Frequency Response Analyser) for TPS63020?
If the answer is yes, could you share it for my customer?
My customer wants to see as a reference.

Best Regards,

  • May I have your comments?
    The background of the request is that my customer evaluates loop stability by FRA however he confirmed there is little phase margin.
    So he wants to confirm if there is any data.

    Best Regards,
    Yaita

  • I could get some data, here is the bode plot of TPS63020 (EVM configuration) at 1.6A load, Vin= 5V and Vout 3.3V:

    What are the operating conditions of the converter in their application? 

  • Hi Sabrina-san,

    I really appreciate for your support!
    I will send the data to my customer.

    I would also like to send my customer's schematic to you off-line.
    Could you send e-mail to the following address?
