Output Voltage Adjustment: The output voltage of the module may be adjusted by using an external resistor connected between the trim pin 6 and either the Sense

(+)or Sense (-) pin. If the voltage trim feature is not used, pin 6 should be left open. Care should be taken to avoid injecting noise into the module’s trim pin. A small 0.01uF capacitor between the power module’s trim pin and Sense (-) pin may help to avoid this.

With a resistor between the trim pin and Sense (-) pin, the output voltage is adjusted down. To adjust the output voltage down a percentage of Vout (%) from Vo,nom, the trim resistor should be chosen according to the following equation:

Rdown = 5.11⋅ (

The current limit set point does not increase as the module is trimmed down, so the available output power is reduced.
