Because the sense lead carries minimal current,
large trace on the end-user board is not required.
However, the sense trace should be located close
to a ground plane to minimize system noise and
insure optimum performance.
When utilizing the remote sense feature, care
must be taken not to exceed the maximum
allowable output power capability of the converter,
equal to the product of the nominal output voltage
and the allowable output current for the given
conditions.
When using remote sense, the output voltage at
the converter can be increased up to 0.5V 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 converter’s
actual output power remains at or below the
maximum allowable output power.
Output Voltage Programming (Pin 9)
The output voltage can be programmed from
0.7525V to 5.5V by connecting an external resistor
between the TRIM pin (Pin 9) and the GND pin
(Pin 5); see Fig. C.
A trim resistor, R
can be calculated using the following equation:

Note that the tolerance of a trim resistor directly
affects
recommended to use standard 1% or 0.5%
resistors; for tighter tolerance, two resistors in
parallel are recommended rather than one
standard value from Table 1.
The ground pin of the trim resistor should be
connected directly to the converter GND pin (Pin
5) with no voltage drop in between. Table 1
provides the trim resistor values for popular output
voltages.
The output voltage can also be programmed by an
external voltage source. To make trimming less
sensitive, a series external resistor (Rext) is
recommended between the TRIM pin and the
programming voltage source. The control voltage
can be calculated by the formula:
