current (originally obtained from the derating curves)
by the same percentage to ensure the converter’s
To decrease the output voltage (Fig. D), a trim
resistor, R T-DECR , should be connected between the
TRIM (Pin 6) and SENSE(-) (Pin 5), with a value of:
actual output power remains at or below the
maximum allowable output power.

Output Voltage Adjust /TRIM (Pin 6)
The output voltage can be adjusted up 10% or down
20%. Trim up to 10% is guaranteed only at Vin ≥
40V, and it is approximately 8% to 10% at Vin = 36V.
The TRIM pin should be left open if trimming is not
being used. To minimize noise pickup, a 0.1 μF
capacitor is connected internally between the TRIM
and SENSE(-) pins.
To increase the output voltage, refer to Fig. C. A trim
where,
R T-DECR = Required value of trim-down resistor [k ? ]
and ? is defined above.
Note:
The above equations for calculation of trim resistor values match
those typically used in conventional industry-standard quarter-
bricks, eighth-bricks and sixteenth-bricks.

condition could cause unwanted triggering of the
output overvoltage protection (OVP) circuit. The
designer should ensure that the difference between
the voltages across the converter’s output pins and
V O ? REQ = Desired (trimmed) output voltage [V].
When trimming up, care must be taken not to exceed
the converter‘s maximum allowable output power.
See the previous section for a complete discussion
of this requirement.

or:
[V OUT ( + ) ? V OUT ( ? )] ? [V SENSE ( + ) ? V SENSE ( ? )] ≤ V O - NOM X 10% [V]
This equation is applicable for any condition of
output sensing and/or output trim.
