VO = Original set-point voltage
Notes:
1. Use only a single 1% resistor in either the R1 or (R2) location. Place the resistor as close to the converter as
possible.
2. If the output voltage is increased, the maximum load current must be derated according to the following
equation.
(3)
Where:
VO = Original set-point voltage
VA = Adjusted output voltage (measured between pins 8 and 4)
In any instance, the load current must not exceed the converter's maximum rated output current of 20 A.
3. The overvoltage threshold is fixed, and is set approximately 20% above the nominal output voltage. Adjusting
the output voltage higher reduces the voltage margin between the adjusted output voltage and the
overvoltage (OV) protection threshold. This could make the module sensitive to OV fault detection, as a
result of random noise and load transients.
