Temperature Derating Curves
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).
Temperature derating for 18-36V and 36- 75V
input voltage ranges :
The 9-36V and 18-75V input voltage versions of
this series feature a 4:1 input voltage range and
can achieve operation at full power at 85ºC
ambient temperature with only convection cooling.
Temperature derating for 9-36V and 18-75V input
voltage ranges :
Typical Application
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 0.47µF ceramic
capacitor (for 3.3V and 5V outputs) or a 0.27µF
ceramic capacitor (for other outputs).
Care must be taken to ensure the maximum rated
output capacitance for the device is not exceed
when dimensioning decoupling capacitors in the
system as this could cause the unit to detect an
overload and enter a ‘hiccup’ mode of operation.

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 100ms until the overload has
cleared.
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%).
Series Operation
The outputs of two units may be connected in series to
achieve a higher system voltage.
Safety Considerations
These converters feature 1500 Volt DC isolation
from input to output. The input to output
resistance is greater than 10MOhm. These
converters are provided with Operational
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.
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 Recommended Fuse
36-75V F0.315A
18-36V F0.5A
9-36V F1.0A
18-75V 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.

Surface Mount Assembly
Soldering:
The following instructions must be observed when
soldering the unit. Failure to observe these
instructions may result in failure or significant
degradation of the module performance. PowerOne will not honor any warranty claims arising
from failure to observe these instructions.
This product is approved for forced convection
reflow soldering only.
The curves below define the maximum peak
reflow temperature permissible measured on
Pins 1 and 10 of the converter.
The lead-frame is constructed for a high
temperature glass filled, UL94V0 flame retardant,
diallyl ortho-phthalate moulding compound
commonly used for packaging of electronics
components. It has passed NASA outgassing
tests and is certified to MIL-M- 14. The coefficient
of thermal expansion is equivalent to FR4.
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. (Dip of Class II or better).
The product is manufactured with a patented
process, which is fully automated, and ‘in-line’.
This ensures that there is no contamination or
mechanical stress on the lead-frame so that the
co planarity and solderability are maintained.
The product is shipped in JEDEC trays to
guarantee preservation of the co- planarity and
enable fully automated assembly in the final
application.
.
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 (> 2.0mm, 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.
