circuit (AC mains) in accordance with IEC/EN/UL 60950-1.
Isolated DC/DC converters
General information
It is recommended that a slow blow fuse is to be used at
the input of each DC/DC converter. If an input filter is used
in the circuit the fuse should be placed in front of the input
filter.
In the rare event of a component problem that imposes a
short circuit on the input source, this fuse will provide the
following functions:
Flex DC/DC converters and DC/DC regulators are
designed in accordance with safety standards
IEC/EN/UL 60950-1 Safety of Information Technology
Equipment.
IEC/EN/UL 60950-1 contains requirements to prevent
injury or damage due to the following hazards:
•
•
•
•
•
•
•
Electrical shock
Energy hazards
Fire
Mechanical and heat hazards
Radiation hazards
Chemical hazards
On-board DC/DC converters and DC/DC regulators are
defined as component power supplies. As components
they cannot fully comply with the provisions of any safety
requirements without “Conditions of Acceptability”.
Clearance between conductors and between conductive
parts of the component power supply and conductors on
the board in the final product must meet the applicable
safety requirements. Certain conditions of acceptability
apply for component power supplies with limited stand-off
(see Mechanical Information for further information). It is
the responsibility of the installer to ensure that the final
product housing these components complies with the
requirements of all applicable safety standards and
regulations for the final product.
Component power supplies for general use should comply
with the requirements in IEC 60950-1, EN 60950-1 and
UL 60950-1 Safety of Information Technology Equipment.
There are other more product related standards, e.g.
IEEE 802.3 CSMA/CD (Ethernet) Access Method, and
ETS-300132-2 Power supply interface at the input to
telecommunications equipment, operated by direct current
(dc), but all of these standards are based on
IEC/EN/UL 60950-1 with regards to safety.
Flex DC/DC converters and DC/DC regulators are
UL 60950-1 recognized and certified in accordance with
EN 60950-1.
The flammability rating for all construction parts of the
products meet requirements for V-0 class material
according to IEC 60695-11-10, Fire hazard testing, test
flames – 50 W horizontal and vertical flame test methods.
The products should be installed in the end-use
equipment, in accordance with the requirements of the
ultimate application. Normally the output of the DC/DC
converter is considered as SELV (Safety Extra Low
Voltage) and the input source must be isolated by
minimum Double or Reinforced Insulation from the primary
•
Isolate the fault from the input power source so
as not to affect the operation of other parts of the
system.
Protect the distribution wiring from excessive
current and power loss thus preventing
hazardous overheating.
The galvanic isolation is verified in an electric strength test.
The test voltage (Viso) between input and output is
1500 Vdc or 2250 Vdc (refer to product specification).
24 V DC systems
The input voltage to the DC/DC converter is SELV (Safety
Extra Low Voltage) and the output remains SELV under
normal and abnormal operating conditions.
48 and 60 V DC systems
If the input voltage to the DC/DC converter is 75 Vdc or
less, then the output remains SELV (Safety Extra Low
Voltage) under normal and abnormal operating conditions.
Single fault testing in the input power supply circuit should
be performed with the DC/DC converter connected to
demonstrate that the input voltage does not exceed
75 Vdc.
If the input power source circuit is a DC power system, the
source may be treated as a TNV-2 circuit and testing has
demonstrated compliance with SELV limits in accordance
with IEC/EN/UL60950-1.
Non-isolated DC/DC regulators
The input voltage to the DC/DC regulator is SELV (Safety
Extra Low Voltage) and the output remains SELV under
normal and abnormal operating conditions.

Operating information
External Decoupling Capacitors
Input Voltage
The input voltage range 36 to 75Vdc meets the requirements
of the European Telecom Standard ETS 300 132-2 for normal
input voltage range in –48 and –60 Vdc systems, -40.5 to 57.0 V and –50.0 to -72 V respectively.
At input voltages exceeding 75 V, the power loss will be
higher than at normal input voltage and Tref must be limited to
absolute max +110°C. The absolute maximum continuous
input voltage is 80 Vdc.
Turn-off Input Voltage
The DC/DC converters monitor the input voltage and will turn
on and turn off at predetermined levels.
The minimum hysteresis between turn on and turn off input
voltage is 3V.
Remote Control (RC)
The products are fitted with a
remote control function referenced
to the primary negative input
connection (- In), with negative and
positive logic options available. The
RC function allows the converter to
be turned on/off by an external
device like a semiconductor or
mechanical switch. The RC pin has
an internal pull up resistor to Vcc
pin of controller IC.
The maximum required sink current is 1 mA. When the RC pin
is left open, the voltage generated on the RC pin is around
6 V. The second option is “positive logic” remote control,
which can be ordered by adding the suffix “P” to the end of
the part number. The converter will turn on when the input
voltage is applied with the RC pin open. Turn off is achieved
by connecting the RC pin to the - In. To ensure safe turn off
the voltage difference between RC pin and the - In pin shall
be less than 1V. The converter will restart automatically when
this connection is opened.
See Design Note 021 for detailed information.
Input and Output Impedance
The impedance of both the input source and the load will
interact with the impedance of the DC/DC converter. It is
important that the input source has low characteristic
impedance. The converters are designed for stable operation
without external capacitors connected to the input or output.
The performance in some applications can be enhanced by
addition of external capacitance as described under External
Decoupling Capacitors. If the input voltage source contains
significant inductance, the addition of a 100 µF capacitor
across the input of the converter will ensure stable operation.
The capacitor is not required when powering the DC/DC
converter from an input source with an inductance below
10 µH.
When powering loads with significant dynamic current
requirements, the voltage regulation at the point of load can
be improved by addition of decoupling capacitors at the load.
The most effective technique is to locate low ESR ceramic
and electrolytic capacitors as close to the load as possible,
using several parallel capacitors to lower the effective ESR.
The ceramic capacitors will handle high-frequency dynamic
load changes while the electrolytic capacitors are used to
handle low frequency dynamic load changes. Ceramic
capacitors will also reduce any high frequency noise at the
load.
It is equally important to use low resistance and low
inductance PCB layouts and cabling.
External decoupling capacitors will become part of the
control loop of the DC/DC converter and may affect the
stability margins. As a “rule of thumb”, 100 µF/A of output
current can be added without any additional analysis. The
ESR of the capacitors is a very important parameter. Power
Modules guarantee stable operation with a verified ESR value
of >10 m across the output connections.
For further information please contact your local Flex
representative.
Output Voltage Adjust (Vadj)
The DC/DC converters have an Output Voltage Adjust pin
(Vadj). This pin can be used to adjust the output voltage above
or below Output voltage initial setting.
When increasing the output voltage, the voltage at the output
pins (including any remote sense compensation ) must be
kept below the threshold of the over voltage protection, (OVP)
to prevent the converter from shutting down. At increased
output voltages the maximum power rating of the converter
remains the same, and the max output current must be
decreased correspondingly.
To increase the voltage the resistor should be connected
between the Vadj pin and +Sense pin. The resistor value of the
Output voltage adjust function is according to information
given under the Output section for the respective product.
To decrease the output voltage, the resistor should be
connected between the Vadj pin and –Sense pin.

Operating information continued
Thermal Consideration
Parallel Operation
General
Two converters may be paralleled for redundancy if the total
power is equal or less than PO max. It is not recommended to
parallel the converters without using external current sharing
circuits.
The converters are designed to operate in different thermal
environments and sufficient cooling must be provided to
ensure reliable operation.
Cooling is achieved mainly by conduction, from the pins to
the host board, and convection, which is dependant on the
airflow across the converter. Increased airflow enhances the
cooling of the converter.
See Design Note 006 for detailed information.
Remote Sense
The DC/DC converters have remote sense that can be used
to compensate for voltage drops between the output and the
point of load. The sense traces should be located close to the
PCB ground layer to reduce noise susceptibility. The remote
sense circuitry will compensate for up to 10% voltage drop
between output pins and the point of load.
If the remote sense is not needed +Sense should be
connected to +Out and -Sense should be connected to -Out.
Over Temperature Protection (OTP)
The converters are protected from thermal overload by the
control IC.
When Tref as defined in thermal consideration section
exceeds 135°C the converter will shut down. The DC/DC
converter will make continuous attempts to start up (nonlatching mode) and resume normal operation automatically
when the temperature has dropped >10°C below the
temperature threshold.
The Output Current Derating graph found in the Output
section for each model provides the available output current
vs. ambient air temperature and air velocity at Vin = 53 V.
The DC/DC converter is tested on a 254 x 254 mm,
35 µm (1 oz), 8-layer test board mounted vertically in a wind
tunnel with a cross-section of 305 x 305 mm.
Proper cooling of the DC/DC converter can be verified by
measuring the temperature at positions P1, P2 and P3. The
temperature at these positions should not exceed the max
values provided in the table below.
Note that the max value is the absolute maximum rating
(non destruction) and that the electrical Output data is
guaranteed up to Tref +90°C.
See Design Note 019 for further information.

Definition of reference temperature (Tref)
The reference temperature is used to monitor the temperature
limits of the product. Temperatures above maximum Tref are
not allowed and may cause degradation or permanent
damage to the product. Tref is also used to define the
temperature range for normal operating conditions.
Tref is defined by the design and used to guarantee safety
margins, proper operation and high reliability of the module.
Ambient Temperature Calculation
By using the thermal resistance the maximum allowed
ambient temperature can be calculated.
1. The power loss is calculated by using the formula
((1/η) - 1) × output power = power losses (Pd).
η = efficiency of converter. E.g 89.0 % = 0.89

0.89
2. 9.26 W × 6.3°C/W = 58.3°C
3. 120 °C – 58.3°C = max ambient temperature is 61.6°C
The actual temperature will be dependent on several factors
such as the PCB size, number of layers and direction of
airflow.

Soldering Information - Surface Mounting
Peak Product Temperature Requirements
The surface mount version of the product is intended for
convection or vapor phase reflow SnPb and Pb-free
processes. To achieve a good and reliable soldering result,
make sure to follow the recommendations from the solder
paste supplier, to use state-of-the-art reflow equipment and
reflow profiling techniques as well as the following guidelines.
Pin number 2 is chosen as reference location for the
maximum (peak) allowed product temperature (TP) since this
will likely be the warmest part of the product during the reflow
process.
A no-clean flux is recommended to avoid entrapment of
cleaning fluids in cavities inside the product or between the
product and the host board. The cleaning residues may affect
long time reliability and isolation voltage.
To avoid damage or performance degradation of the product,
the reflow profile should be optimized to avoid excessive
heating. A sufficiently extended preheat time is recommended
to ensure an even temperature across the host PCB, for both
small and large devices. To reduce the risk of excessive
heating is also recommended to reduce the time in the reflow
zone as much as possible.
Minimum Pin Temperature Recommendations
Pin number 4 is chosen as reference location for the minimum
pin temperature recommendations since this will likely be the
coolest solder joint during the reflow process.
Pin 2 for measurement of maximum
peak product reflow temperature, TP
SnPb solder processes
For SnPb solder processes, the product is qualified for MSL 1
according to IPC/JEDEC standard J-STD-020C.

Dry Pack Information
The surface mount versions of the products are delivered in
trays These inner shipment containers are dry packed in
standard moisture barrier bags according to IPC/JEDEC
standard J-STD-033 (Handling, packing, shipping and use of
moisture/reflow sensitivity surface mount devices).
Using products in high temperature Pb-free soldering
processes requires dry pack storage and handling. In case
the products have been stored in an uncontrolled
environment and no longer can be considered dry, the
modules must be baked according to J-STD-033.
