TPS548B28: TPS548B28 Vout accuracy

Part Number: TPS548B28

Hi,

could you tell me the Vout accuracy of TPS548B28? does this same as the SS/REFIN-to-FB Accuracy mentioned in the datasheet?

Thanks.

  • The internal voltage reference is 0.6V   +/-1% over the temperature range .   

    The output accuracy when using an external reference is +/-0.6% (SS/REFIN-to-FB Accuracy)

    plus the external reference accuracy. 

    The output accuracy will depend on the output voltage, internal reference accuracy, resistor tolerance and the SS/REFIN to FB accuracy using an external reference.

    %Vo = %VREF + 2/(1+Rfbls/Rfbls)*%Rtol  see page 26 of www.ti.com/.../slup207.pd
