OUTPUT VOLTAGE ADJUSTMENT

Output voltage trim allows the user to increase or decrease the output voltage of a module. This is accomplished by connecting an

external resistor between the Trim pin and either the +Vout or –Vout pins. With an external resistor between the Trim and –Vout pins,

the output voltage increases. With an external resistor between the Trim and +Vout pins, the output voltage set-point decreases.
