TPS7A52-Q1: Feedback voltage initial tolerance

Matth. B.

Part Number: TPS7A52-Q1

Dear,

I'm unable to find the initial tolerance of the feedback voltage in the datasheet of the component, there is only a typical value.

Could someone give me the min and max value?

Regards

Hi Matthieu,

You can use the tolerances shown in this table as representative of the FB pin voltage min and max value.

Thanks,

Hello Stephen,

I agreen but these tolerances include voltage, load current and temperature variations.

I wanted just initial tolerance at a fixed point in order of voltage, load and temperature.

Thanks

Hi Matthieu,

I have reviewed the archives, but I do not see characterization data which describes a tolerance for one Vin, one Vout, one load and one temperature.
It is fairly common to use the design table I provided for the statistical analysis of a setpoint, as it includes numerous steady state parameter variations (line regulation, Iout load regulation, reference variation, temperature variation).

Thanks,

- Stephen
