Feature Descriptions
Overcurrent Protection
To provide protection in a fault (output overload) condi-
tion, the unit is equipped with internal current-limiting
circuitry and can endure an overcurrent condition indef-
initely.
At the point of current-limit inception, the unit shifts
from voltage control to current control. If the output volt-
age is pulled very low during a severe fault, the current-
limit circuit can exhibit either foldback or tailout charac-
teristics (output current decrease or increase).
The unit will try to restart after an overcurrent shut
down. If the output overload condition still exists when
the unit restarts, it will shut down again. This operation
will continue indefinitely until the overcurrent condition
is corrected.
Remote On/Off
Two remote on/off options are available. Positive logic
remote on/off turns the module on during a logic-high
voltage on the ON/OFF pin, and off during a logic low.
Negative logic remote on/off turns the module off dur-
ing a logic high and on during a logic low. Negative
logic, device code suffix “1,” is the factory-preferred
configuration.
To turn the power module on and off, the user must
supply a switch to control the voltage between the
on/off terminal and the V

Remote Sense
Remote sense minimizes the effects of distribution
losses by regulating the voltage at the remote-sense
connections. The voltage between the remote-sense
pins and the output terminals must not exceed the out-
put voltage sense range given in the Feature Specifica-
tions table, i.e.:
[V
O
(+) – V
O
(–)] – [SENSE(+) – SENSE(–)]
≤
0.5 V
The voltage between the V
must not exceed the minimum output overvoltage pro-
tection voltage as indicated in the Feature Specifica-
tions table. This limit includes any increase in voltage
due to remote-sense compensation and output voltage
set-point adjustment (trim). See Figure 13.

output at the point of load, then connect SENSE(+) to
