    Hi Rakxit,

    Thanks for the above query. For this device, WEBENCH calculates Vout tolerance for worst case(Maximum %) by considering Feedback divider resistor tolerance % and Vout accuracy of the device.

    Vout accuracy considered for calculation:

    Please find the below app note for your reference,  Vout tolerance calculation on WEBENCH is similar to this.

    Vout tolerance for default WEBENCH design for TPS62130 is 2.94% . We could not verify 1.972% mentioned in above post.
