3 Output Voltage Adjustment Range
Output voltage can be adjusted by using the trim function.
There are 2 options available for the trim function, which
are
a） Standard Model Trim : 2 independent trim to adjust
each output voltage individually. Note that the height
of power module is 8.9mm.
When both output voltage trim function are being use,
make sure that Vo1–Vo2 is always equal or larger than
0.5V; (Vo1–Vo2≧0.5V). The allowable trim range for
both output are as shown in the next page; Page 7,
Figure3-1.
b） /C Option Model Trim: A single trim to adjust both the
output voltage simultaneously. Note that the height for
this option model is 10.2mm. This model is compatible
to other manufacturers power module.
Note:
a） OVP might trigger when output voltage adjustment exceeds
the maximum allowable range specified in the following
section.
b） Output under voltage protection for Vo1 might trigger if Vo1
is decreased below the minimum allowable range.
c） When increasing the output voltage, reduce the output cur-
rent accordingly so as not to exceed the maximum output
power.
d） When decreasing the output voltage, the allowable output
current is the same as nominal voltage output current.

Fig.3-1: PAQ65D48 Standard Model Trim Range
3.1 Standard Model Trim
As mentioned above the standard product comes with 2
independent trim pins to adjust each output voltage indi-
vidually. Vo1/Vo2 output voltage can be adjusted by con-
necting an external resistor (Radj) between TRM1/TRM2
to either
a） Vo1/Vo2 terminal: to adjust to higher output voltage;
Fig. 3-2 or
b） GND terminal: to adjust to lower output voltage; Fig.
3-3.

The required external resistor values to tune up or down
the output voltage for the respective standard models can
be found in Page 9 and 10.
3.2 /C Option Model Trim
This option model comes only with one trim pin to adjust
both the output voltage simultaneously. Note that the
height for this option model is 10.2mm. This model is
compatible to other manufacturers power module.
