ity of the converter, equal to the product of the nominal out-
put voltage and the allowable output current for the given
conditions.
When using remote sense, the output voltage at the con-
verter can be increased by as much as 10% above the
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.
Output Voltage Adjust /TRIM (Pin 6)
The converter’s output voltage can be adjusted up 10% or
down 20% for Vout
≥ 1.5 V, and ±10% for Vout = 1.2 V and
1.0 V relative to the rated output voltage by the addition of
an externally connected resistor. For output voltage 3.3 V,
trim up to 10% is guaranteed only at Vin
≥ 40 V, and it is
marginal (8% to 10%) at Vin = 36 V.
The TRIM pin should be left open if trimming is not being
used. To minimize noise pickup, a 0.1 F capacitor is con-
nected internally between the TRIM and SENSE(-) pins.
To increase the output voltage, refer to Fig. C. A trim resis-
tor, RT-INCR, should be connected between the TRIM (Pin 6)
and SENSE(+) (Pin 7), with a value of:

Note: The above equations for calculation of trim resistor
values match those typically used in conventional industry-
standard quarter bricks and one-eighth bricks (except for
1.2 V and 1.0 V outputs).
Converters with output voltages 1.2 V and 1.0 V are avail-
able with alternative trim feature to provide the customers
with the flexibility of second sourcing. For these converters,
the last character in the part number is “T”. The trim equa-
tions of “T” version of converters and more information can
be found in Application Note 103.
