Output Voltage Adjustment
Output voltage s
et point adjustment allows 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 SENSE(+)
or
SENSE(-) pins.With an external resistor between the TRIM and SENSE(-)
pin, the output voltage set point increases.
With an external resistor between the TRIM andSENSE(+) pin, the output voltage set point decreases.
