Feature Descriptions
Output Voltage Set-Point Adjustment
(Trim)
Output voltage trim allows the user to increase or
decrease the output voltage set point of a module. This
is accomplished by connecting an external resistor
between the TRIM pin and either the SENSE(+) or
SENSE(–) pins. With an external resistor between the
TRIM and SENSE(–) pins (R
set point (V
lowing equation determines the required external-resis-
tor value to obtain an output voltage change of %ý.
For example, to lower the output voltage by 30%, the
external resistor value must be:
With an external resistor connected between the TRIM
and SENSE(+) pins (R
point (V
equations determine the required external-resistor
value to obtain an output voltage change of %ý.

The combination of the output voltage adjustment and
sense range and the output voltage given in the Fea-
ture Specifications table cannot exceed 110% of the
nominal output voltage between the V
terminals.
The JW030-Series Power Modules have a fixed cur-
rent-limit set point. Therefore, as the output voltage is
adjusted down, the available output power is reduced.
In addition, the minimum output current is a function of
the output voltage. As the output voltage is adjusted
down, the minimum required output current can
increase.

Output Overvoltage Protection
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.
