OUTPUT VOLTAGE ADJUSTMENT

Output voltage is adjustable for 10% trim up or -20 trim down of nominal output voltage by connecting an external resistor between the

Trim pin and either the +Sense pins.

With an external resistor between the Trim and –Sense pin, the output voltage set point decreases.

With an external resistor between the Trim and +Sense pin. The output voltage set point increases.

Maximum output deviation is +10% inclusive of remote sense.

The external TRIM resistor needs to be at least 1/8W of rated power.
