Output Voltage Adjustment
Output voltage set point adjustment allo
ws the user to increase or decrease the output voltage set point of a
module. 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 TRIMand Vo(-) pin, the out
put voltagesetpoint increases.With an external
resistor between theTRIMand Vo(+) pin, theoutput voltage set point decreases.
