TYPICAL CHARACTERISTIC CURVES
7.1
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 or 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.
7.2
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.
7.3
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).
7.4
The outputs of two units may be connected in series to achieve a higher system voltage.

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 – 36 V and 36 – 75 V input voltage ranges:
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.

These converters are tested with 1500 VDC from input to output. The input-to-output resistance is greater than 10 MΩ. These
converters are provided with Basic Insulation between input and output. 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 application must be observed.
In order to consider the output of the converter as SELV (Safety Extra Low Voltage) or TNV-1, according to IEC/EN 60950-1 and
UL/CSA 60950-1, one of the following requirements must be met in the system design:
(i) Fuse: The converter has no internal fuse. An external fuse must be provided to protect the system from catastrophic failure.
Recommended fuses are listed in the table below:
INPUT VOLTAGE RANGE
RECOMMENDED FUSE
36 – 75V
F0.315A
18 – 36V
F0.5A
9 – -6V
F1.0A
18 – -5V
F0.5A
(ii) The user can select a lower rating fuse based upo the inrush transient and the maximum input curren of the converter, which
occurs at the minimu 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.
(iii) If the voltage source feeding the module is SELV, TNV-1, or TNV-2, the output of the converter is considered SELV and may
be grounded or ungrounded.
(iv) 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.
10.1
The converters meet the requirements of EN 55011/55022, (conducted noise on the input terminals) without any external
components. The results for this solution are displayed below.
To meet class B for the above standards, it is necessary to fit a 3.3 μF ceramic capacitor across the input terminals.

The following soldering instructions must be observed to prevent failure or significant degradation of the module
performance. Power Bel Solutions will not honor any warranty claims arising from failure to observe these instructions. The
lead-frame is constructed for a high temperature glass filled, UL94 V-0 flame retardant, dually orthophthalate molding
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 visual inspection (manual or automatic). The leads are formed
from a 97 Cu alloy plated with Ni and matte Sn. 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 ensure preservation of
the co-planarity and enable fully automated assembly in the final application. Mind the marking for pin 1! These products
are approved for forced convection reflow soldering only. Products RoHS-compliant for all 6 substance (model designation
ending with -M6G) allow for a solder profile with higher temperatures; see tables below.

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.
