8.2.2.5 Determine the Value of R1 and R2
The output voltage is programmed by the voltage-divider resistors, R1 and R2, shown in Equation 12. Connect R1 between the VFB pin and the output, and connect R2 between the VFB pin and GND. The recommended R2 value is from 1 kΩ to 20 kΩ. Determine R1 using Equation 12.
Equation 12.
