External trim adjustment

Output voltage set point adjustment al

lows 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 TRIM and Vo (+) pin, the output voltage set point decreases. With an external resistor between the TRIM and Vo (-

) pin,

theoutput voltageset point increases.
