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 ≥
37.5V, 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.
R T-DECR = Required value of trim-down resistor [k ? ]
and Δ 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.

To increase the output voltage, refer to Fig. C. A trim
resistor, RT-INCR, should be connected between the
TRIM (Pin 6) and SENSE(+) (Pin 7), with a value of:

V O ? REQ ? Desired (trimmed) output voltage [V].
Trimming/sensing beyond 110% of the rated output
voltage is not an acceptable design practice, as this
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
its sense pins does not exceed 10% of V OUT (nom),
or:
[V OUT ( ? ) ? V OUT ( ? )] ? [V SENSE ( ? ) ? V SENSE ( ? )] ? V O - NOM X 10% [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.
This equation is applicable for any condition of
output sensing and/or output trim.
