Feature Descriptions
Output Overvoltage Clamp
The output overvoltage clamp consists of control cir-
cuitry, independent of the primary regulation loop, that
monitors the voltage on the output terminals. The con-
trol loop of the clamp has a higher voltage set point
than the primary loop (see Feature Specifications
table). This provides a redundant voltage control that
reduces the risk of output overvoltage.
Current Limit
To provide protection in a fault (output overload) condi-
tion, the unit is equipped with internal current-limiting
circuitry. At the point of current-limit inception, the unit
shifts from voltage control to current control. If the out-
put voltage is pulled very low during a severe fault, the
current-limit circuit can exhibit either foldback or
tailout characteristics (output current decrease or
increase). The unit operates normally once the output
current is brought back into its specified range.
Output Voltage Set-Point Adjustment
The output voltage adjustment feature provides the
capability of increasing or decreasing the output volt-
age set point of a module. This can be accomplished
by using an external resistor connected between the
TRIM pin and either the V

pins (R

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 REMOTE ON/OFF pin, and off during a
logic low. Negative logic remote on/off, suffix code “1,”
turns the module off during a logic high and on during a
logic low.
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
can be an open collector or equivalent (see Figure 21).
A logic low is V
during a logic low is 1 mA. The switch should maintain
a logic low voltage while sinking 1 mA.
During a logic high, the maximum V
the power module is 10 V. The maximum allowable
leakage current of the switch at V
