To change the output voltage of the EVM, it is necessary to change the value of resistor R8 and R9. R13 is fixed at 10 kΩ. Changing the total value of R8 plus R9 can change the output voltage above the 0.6-V reference voltage V_INTREF. A two resistor configuration of R8 + R9 is implemented to give the exact desired output voltage setting. The value of R8 and R9 for a specific output voltage can be calculated using Equation 1.

where

• V_INTREF = 0.6 V
• R_{FB_HS} = R₈+ R₉
• R_{FB_LS} = R₁₃ = 10 kΩ
