Output Voltage Programing

The output voltage of the power converter is set by using a resister divider from of the converter to the VSENSE pin. For a selected value of , the value of can be found using Equation 7.

Equation 13. R b o t t o m =   V r e f   V o u t -   V r e f x   R t o p = 0.613   V   1   V   -   0.613   V x   10   k Ω =   15.8   k Ω
