Fig. 13B. Configuration for decreasing output
voltage
To decrease the output voltage, a trim resistor RT-
DEC R, (Fig. 13B) should be connected between the
TRIM (Pin 6) and Vout2(+) pin (Pin 7), with a
value from the table below, where:
?
=
percentage
of
increase
or
decrease
Vout(NOM).
Models using the trim configuration shown in
figure
13B
include:
Q2D30ZEB,
Q2D30ZEY,
Q2D30ZDB, Q2D30ZBA.
Note 1: Both outputs are trimmed up or down
simultaneously.

Note 2: The above trim resistor values match
those typically used in industry-standard dual
quarter bricks.
Input Under-Voltage Lockout
Input under-voltage lockout is standard with this
converter. The converter will shut down when the
input
voltage
drops
below
a
predetermined
voltage.
The input voltage must be at least 35V for the
converter to turn on. Once the converter has been
turned on, it will shut off when the input voltage
drops below 31V. This feature is beneficial in
preventing deep discharging of batteries used in
telecom applications.
