TPS659037: limitation of PMIC_SMPS's Inrush current

Part Number: TPS659037

Hi all

Would you mind if we ask TPS659037?

Is there the limitation of PMIC_SMPS's Inrush current?
As the background of this question, there are limitations for current-limit and Iomax, however there are limitations for Inrush current.

Kind regards,

Hirotaka Matsumoto

    Hi Matsumoto-san,

    I can confirm that SMPS inrush current is not a specified electrical characteristic for the TPS659037 therefore we do not have a characterized limit on the inrush current.

    The device has internal soft-start on the SMPS rails to prevent large inrush currents.

    I have assigned this post to Nastasha if you have follow up questions, so please allow for some delay as she will not be back until Jan 3rd.
