Feature Descriptions
Output Voltage Set-Point Adjustment
(Trim)
Although the output voltage can be increased by both
the remote sense and by the trim, the maximum
increase for the output voltage is not the sum of both.
The maximum increase is the larger of either the
remote sense or the trim. Consult your Tyco Electron-
ics’ Account Manager or Application Engineer if the
output voltage needs to be increased more than the
above limitation.
The amount of power delivered by the module is
defined as the voltage at the output terminals multiplied
by the output current. When using remote sense and
trim, the output voltage of the module can be
increased, which at the same output current would
increase the power output of the module. Care should
be taken to ensure that the maximum output power of
the module remains at or below the maximum rated
power.

Output Overvoltage Protection
The output overvoltage clamp consists of control
circuitry, independent of the primary regulation loop,
that monitors the voltage on the output terminals. This
control loop has a higher voltage set point than the
primary loop (see the Feature Specifications table). In
a fault condition, the overvoltage clamp ensures that
the output voltage does not exceed V
provides a redundant voltage-control that reduces the
risk of output overvoltage.
Overtemperature Protection
These modules feature overtemperature protection to
safeguard the modules against thermal damage.
When the temperature exceeds the overtemperature
threshold given in the feature specifications table, the
module will limit the available output current in order to
help protect against thermal damage. The overcurrent
inception point will gradually move back to its original
level as the module is cooled below the overtempera-
ture threshold.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout
limit, the module operation is disabled. The module will
begin to operate at an input voltage between the under-
voltage lockout limit and the minimum operating input
voltage.
