OUTPUT VOLTAGE ADJUSTMENT

Output 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 or –SENSE pins. With an external resistor between the TRIM and –SENSE pin, the output voltage set

decreases. With an external between the TRIM and –SENSE pin, the output voltage set point increases. Maximum output deviation is

+10% inclusive of remote sense. The value of the external resistor can be obtained by the equations below. The external TRIM resistor

needs to be at least 1/8W resistor.
