The derating curves below give an indication of the
output power achievable with and without forced-air
cooling. However in the final application the
temperature rise of the converter is also influenced
by factors such as heat conduction through the leads
to the PCB, orientation, the temperature of
surrounding components and the input voltage. To
ensure the reliability of the converter, care must be
taken to guarantee that the maximum case
temperature is not exceeded under any conditions.
The measurement point for case temperature is
specified on the mechanical drawing (Tc).

Ambient Temp. (deg °C)
The 9-36 V and 18-75 V input voltage versions of this
series feature a 4:1 input voltage range and can
operate at full power at 85 ºC ambient temperature
with only convection cooling.
APR 20, 2006 revised to MAR 12, 2007
This series of converters does not require any
external components for proper operation. However,
if the distribution of the input voltage to the converter
contains significant inductance, a capacitor across
the input terminals may be required to stabilize the
input voltage.
A minimum of 0.47μF, quality
electrolytic / ceramic capacitor is recommended for
this purpose.
For output decoupling it is
recommended to connect, directly across the output
pins, a 0.47 μF ceramic capacitor (for 3.3 V and 5 V
outputs) or a 0.27 μF ceramic capacitor (for other
outputs).
Care must be taken to ensure the maximum rated
output capacitance for the device is not exceeded
when dimensioning decoupling capacitors in the
system as this could cause the unit to detect an
overload and enter a ‘hiccup’ mode of operation.

NV DC-DC Series Data Sheet
6W SMT Converter • Wide Input • 3.3V to +/-24V Outputs
Output Current Limiting
When the output is overloaded above the maximum
output current rating, the voltage will start to reduce
to maintain the output power to a safe level. In a
condition of high overload or short-circuit where the
output voltage is pulled below approximately 30% of
Vo.nom, the unit will enter a ‘Hiccup’ mode of
operation. Under this condition the unit will attempt
to restart, approximately every 100 ms until the
overload has cleared.
In order for the output of the converter to be
considered as SELV (Safety Extra Low Voltage) or
TNV-1, according to EN60950
/ UL1950 /
CSA60950-00, one of the following requirements
must be met in the system design:
• The converter has no internal fuse. An external
fuse must be provided to protect the system from
catastrophic failure. The recommended fuse
values are shown below:
Input Voltage Range
36-75V
18-36V
9-36V
18-75V
Parallel Operation
Paralleling of two converters is possible by direct
connection of the output voltage terminal pins. The
load regulation characteristic is designed to facilitate
current sharing (typically ± 20%).
However, this may cause start-up problems at initial
start-up, and is only recommended in applications
where one converter is able to deliver the full load
current (true redundant systems).
Series Operation
The outputs of two units may be connected in series
to achieve a higher system voltage.
Safety Considerations
These converters feature 1500 VDC isolation from
input to output. The input-to-output resistance is
greater than 10MΩ. These converters are provided
with Basic Insulation between input and output
circuits according to EN60950 / UL1950 /
CSA60950-00. Nevertheless, if the system using
the converter needs to receive safety agency
approval, certain rules must be followed in the design
of the system. In particular, all of the creepage and
clearance requirements of the end-use safety
requirements must be observed. These documents
include UL60950, CSA60950-00 and EN60950,
although specific applications may have additional
requirements.
APR 20, 2006 revised to MAR 12, 2007
Recommended Fuse
F0.315A
F0.5A
F1.0A
F0.5A
• The user can select a lower rating fuse based
upon the inrush transient and the maximum input
current of the converter, which occurs at the
minimum input voltage. Both input traces and the
chassis ground trace (if applicable) must be
capable of conducting a current of 1.5 times the
value of the fuse without opening. The fuse must
not be placed in the grounded input line, if any.
• If the voltage source feeding the module is SELV,
the output of the converter is considered SELV
and may be grounded or ungrounded.
• The circuitry of the converter may generate
transients, which exceed the input voltage. Even
if the input voltage is SELV (<60V) the
components on the primary side of the converter
may have to be considered as hazardous. A
safety interlock may be needed to prevent the
user from accessing the converter while
operational.

commonly used for packaging of electronics
components. It passes NASA outgassing tests and
is certified to MIL-M-14. The coefficient of thermal
expansion is equivalent to FR4.
The product is manufactured with a patented
process, which is fully automated, and ‘in-line’. This
ensures that there is no contamination or

The curves below define the maximum peak reflow
temperature permissible measured on Pins 1 and 13
of the converter.
The gull wing leads are formed to ensure optimal
solder joint strength and structure. Furthermore
they facilitate optical inspection (manual or
automatic). The leads are formed from a 97% Cu
alloy plated with Cu and Sn 90. This material is
commonly used in the manufacture of integrated
circuits. It has good corrosion resistance and
exhibits the nobility inherent to all high copper
alloys. Unlike brasses, this material is essentially
immune to stress corrosion cracking. It also exhibits
excellent solderability. It is readily wetted by solders
and performs well in standard solderability tests.

Pick & Place Assembly:
The product is designed with a large flat area in the
center of the top surface to serve as a pick up point
for automated vacuum pick and place equipment.
The ‘open board’ construction of the unit ensures
that weight is kept to a minimum. However due to the
relatively large size of the component, a large nozzle
(> 6.0mm, depending on vacuum pressure) is
recommended for picking and placing.
The unit may also be automatically handled using
‘odd-form’ placement equipment, with mechanical
grippers. For this type of equipment the end edges
of the device, which have no leads and also feature
the greatest dimensional accuracy, should be used
as pick-up points.
