The trim equation for the basic configuration shown in Figure 5 is:
Where Vout is the desired output voltage and Rtrim is the resistance required between the Trim pin and
-Sense.
The trim equation for the external voltage configuration shown in Figure 6 is:
Where Vout is the desired output voltage, R trim1 (kΩ) and R trim2 (kΩ) are the resistors in Figure 6 and
Vt is the applied external output voltage.
