Output Trim Equations
Equations for calculating the trim resistor (in k) are shown below. The Trim Down resistor should be connected
between the Trim pin and Ground pin. The Trim Up resistor should be connected between the Trim pin and the
Vout. Only one of the resistors should be used for any given application.
Notes:
Vo_req=Desired(trimmed) output voltage[V]
Output voltage Vo=3.308V for 3.3V output; Vo=5.000V for 5.0V; Vo=12.000V for 12V output
