External trim adjustment
Outp
ut voltage set point adjustment allows the usertoincrease ordecrease theoutput voltage set point ofamodule. This is
accomplished by connecting an external resistor between the TRIM pin and either the Vo (+) or Vo (-
) pins. With an external resistor
between theTRIMand Vo (+) pin, the output voltage set point decreases.With an external resistor between the TRIMand Vo (-
) pin,
theoutput voltageset point increases.
