2:1 Wide Input Voltage Range
OUTPUT VOLTAGE ADJUSTMENT
Output voltage set 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 +OUTPUT or -OUTPUT pins. With an
external resistor between the TRIM and -OUTPUT pin, the output voltage set point increases. With an external resistor
between the TRIM and +OUTPUT pins, the output voltage set point decreases. The external TRIM resistor needs to be at
least 1/16W resistors.
