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.
