FEATURES DESCRIPTIONS (CON.) Output Voltage Adjustment (TRIM) To increase or decrease the output voltage set point, the modules may be connected with an external resistor between the TRIM pin and either the SENSE(+) or SENSE(-). The TRIM pin should be left open if this feature is not used. Figure 19: Circuit configuration for trim-up (increase output voltage) If the external resistor is connected between the TRIM and SENSE (+) the output voltage set point increases (
