The output voltage is set with a resistor divider created by R8 (RFBT) and R6 (RFBB) from the output node to the FB pin. It is recommended to use 1% tolerance or better resistors. For this example design, 6.04 kΩ was selected for R8. Using Equation 24, R6 is calculated as 12.08 kΩ. The nearest standard 1% resistor is 12.1 kΩ.
