For other output voltages, the value of the required adjust resistor may be calculated using Equation 1.
Table 2 gives the output voltage adjust range and the required equation constants for the converter model
selected. To calculate the required value of RSET, simply locate the applicable constants and substitute these into
the formula along with the desired output voltage.
