Adjusting the Output Voltage of the PT4500/
PT4520 Series of Isolated DC/DC Converters
The factory pre-set output voltage of TI’s PT4500 and
PT4520 series of isolated DC/DC converters may be
adjusted within a nominal ±10% range. Adjustment is made
from the secondary side of the regulator
1
with a single
external resistor. For the input voltage range specified in
the data sheet Table 2-1 gives the allowable adjustment
range for each model, as V
o
(min) and V
o
(max).
Adjust Up:
An increase in the output voltage is obtained
by adding a resistor, R
2
between V
o
Adjust (pin 12), and
–V
out
(pin 7, 8).
Adjust Down:
Add a resistor
(R
1
)
, between V
o
Adjust (pin 12),
and +V
out
(pin 9, 10).
Refer to Figure 2-1 and Table 2-2 for both the placement
and value of the required resistor,
(R
1
)
or R
2
.
Notes:
1.
The PT4500 and PT4520 series of DC/DC converters
incorporate isolation between the ±V
in
and ±V
o
terminals. Adjustment of the output voltage is made
to the regulation circuit on the secondary or output
side of the converter.
2. The maximum rated output power for this series is
20W. An increase in the output voltage may therefore
require a corresponding reduction in the maximum
output current (
see Table 2-1
). The revised maximum
output current must be determined as follows.
=20 A,
or 5A, whichever is less.
V
a
Where V
a
is the adjusted ouput voltage.
3.
Use only a single 1% resistor in either the
(R
1
)
or R
2
location. Place the resistor as close to the module as
possible.

capacitance added to the V
