Output voltage set point adjustment allows the user to increase or decrease the output voltage set point of a
converter. This is accomplished by connecting an external
resistor between the TRIM pin and either the Vo (+) or Vo
(-) pins. With an external resistor between the TRIM and Vo (-
external resistor between the TRIM and Vo (+) pin, the output voltage set point decreases.
