www.ti.comThis adds less than 1% inaccuracy to the voltage measurement and for the calculation of the feedback divider, the current into the feedback pin can be neglected. The current also can be a lot higher. The only disadvantage of smaller resistor values is a higher power loss in the resistive divider, but the accuracy is increased a little.

www.ti.comThis calculation results in a minimum value because choosing any value lower for RPull-up causes a higher current than the test condition current to flow in Q1. If a current higher than the test condition current flows through Q1, the voltage drop across Q1 is higher and no longer ensured. The results of Equation 4 and
