Fig. B: Remote sense circuit configuration.
Because the sense lead carries minimal current,
large trace on the end-user board are not required.
However, 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 0.5 V 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 3)
The output voltage can be programmed from
0.7525 V to 5.5 V by connecting an external resistor
between TRIM pin (Pin 3) and GND pin (Pin 5); see
Fig. C.
A trim resistor, RTRIM, for a desired output voltage
can be calculated using the following equation:

Note that the tolerance of a trim resistor directly
affects
the
output
voltage
tolerance.
It
is
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.
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 be also programmed by
external voltage source. To make trimming less
sensitive, a series external resistor Rext is
recommended between TRIM pin and programming
voltage source. Control Voltage can be calculated by
