TPS62065-Q1: About min and max value of Vref

Part Number: TPS62065-Q1

The Vref parameter is described on page 5 of the TPS 62065-Q1 datasheet.
Typical values are listed here.
However, min and max values are not listed.

Could you provide information on the min and max values of Vref?

  • This is shown in the very next row in the spec table.

    Thank you for your reply.

    I could not find "spec table".
    I might not understand your answers correctly.

    Please tell me where "spec table" points.
    (What page of the TPS62065-Q1 datasheet should be referred to?)

    This is on the same page 5, in the very next row below the Vref spec.

    Thank you for your help.

    I am referencing a TPS62065-Q1 datasheet that can be downloaded from the TI page.

    "VFB(PWM)" is listed on the next line of the Vref spec.
    Is the min (-1.5%) and max (1.5%) listed are min and max of Vref?

    Vref(Typ):600mV
    Vref(min):609mV
    Vref(min):591mV

    Is this understanding correct?

    Yes.

    I think that you are trying to calculate the output voltage accuracy? In this case, it does not matter what the internal voltage's tolerances are. What matters is how well the device regulates the FB pin, since this is how Vout is derived. This is what we specify.
