nominal rating in order to maintain the required voltage
across the load. Therefore, the designer must, if necessary,
decrease the maximum current (originally obtained from the
derating curves) by the same percentage to ensure the con-
verter’s actual output power remains at or below the maxi-
mum allowable output power.

The converter’s output voltage can be adjusted up 10% or
down 20% relative to the rated output voltage by the addition
of an externally connected resistor. Trim up to 10% is guar-
anteed only at Vin ≥ 20 V, and it is marginal (8% to 10%) at
Vin = 18 V.
The TRIM pin should be left open if trimming is not being
used. To minimize noise pickup, a 0.1 μ F capacitor is con-
nected internally between the TRIM and SENSE(-) pins.
To increase the output voltage, refer to Fig. 4. A trim resistor,
R T-INCR , should be connected between the TRIM (Pin 6) and
SENSE(+) (Pin 7), with a value of:

where,
R T ? DECR = Required value of trim-down resistor [k ? ]
and ? is as defined above.
Note: The above equations for calculation of trim resistor
values match those typically used in conventional industry-
standard quarter bricks.

Trimming/sensing beyond 110% of the rated output voltage
is not an acceptable design practice, as this condition could
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 previous
section for a complete discussion of this requirement.
To decrease the output voltage (Fig. 5), a trim resistor,
R T-DECR , should be connected between the TRIM (Pin 6) and
SENSE(-) (Pin 5), with a value of:
cause unwanted triggering of the output over-voltage protec-
tion (OVP) circuit. The designer should ensure that the dif-
ference between the voltages across the converter’s output
pins and its sense pins does not exceed 0.33 V, or:
[V OUT ( + ) ? V OUT ( ? )] ? [V SENSE ( + ) ? V SENSE ( ? )] ≤ 0.33 [V]
This equation is applicable for any condition of output sens-
ing and/or output trim.
