4.2 Output Voltage Setpoint
To change the output voltage of the Evaluation Board, it is necessary to change the value of resister R-FB1~R-FB4.
The values of R-FB1~R-FB4 for a specific output value can be calculated using Equation (1).
For output voltage from 0.75V to 5.5V:
Table 8 lists the R-FB1~R-FB4 values for some common output voltage.
Vout=
(R-FB3 + R-FB4)
(R-FB1 + R-FB2 + R-FB3 + R-FB4)
x 0.6
