OUTPUT VOLTAGE ADJUSTMENT
Output voltage set point adjustment allows the user to increase or decrease the output voltage set point of the 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 Trip and –Vout, the output voltage set point increases.
With an external resistor between the Trim and +Vout, the output voltage set point decreases.
The external Trim resistor needs to be at least 1/16W of rated power.
EXTERNAL OUTPUT TRIMMING
Output can be externally trimmed by using the method shown below.
