Warranty
Warranty period and conditions are defined in Ericsson
Power Modules General Terms and Conditions of Sale.
Reliability
The Mean Time Between Failure (MTBF) is calculated at full
output power and an operating ambient temperature (TA) of
+40°C, which is a typical condition in Information and
Communication Technology (ICT) equipment. Different
methods could be used to calculate the predicted MTBF
and failure rate which may give different results. Ericsson
Power Modules currently uses Telcordia SR332.
Limitation of Liability
Ericsson Power Modules does not make any other
warranties, expressed or implied including any warranty of
merchantability or fitness for a particular purpose
(including, but not limited to, use in life support
applications, where malfunctions of product can cause
injury to a person’s health or life).
Predicted MTBF for the series is:
-
1.4 million hours according to Telcordia SR332, issue
1, Black box technique.
Telcordia SR332 is a commonly used standard method
intended for reliability calculations in ICT equipment. The
parts count procedure used in this method was originally
modelled on the methods from MIL-HDBK-217F, Reliability
Predictions of Electronic Equipment. It assumes that no
reliability data is available on the actual units and devices
for which the predictions are to be made, i.e. all predictions
are based on generic reliability parameters.
Compatibility with RoHS requirements
The products are compatible with the relevant clauses and
requirements of the RoHS directive 2002/95/EC and have a
maximum concentration value of 0.1% by weight in
homogeneous materials for lead, mercury, hexavalent
chromium, PBB and PBDE and of 0.01% by weight in
homogeneous materials for cadmium.
Exemptions in the RoHS directive utilized in Ericsson
Power Modules products include:
-
Lead in high melting temperature type solder (used to
solder the die in semiconductor packages)
Lead in glass of electronics components and in
electronic ceramic parts (e.g. fill material in chip
resistors)
-
-
Lead as an alloying element in copper alloy containing
up to 4% lead by weight (used in connection pins
made of Brass)

Safety Specification
Isolated DC/DC converters
It is recommended that a slow blow fuse with a rating
twice the maximum input current per selected product 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.
General information
Ericsson Power Modules DC/DC converters and DC/DC
regulators are designed in accordance with safety
standards IEC/EN/UL60950, Safety of Information
Technology Equipment.
In the rare event of a component problem in the input filter
or in the DC/DC converter that imposes a short circuit on
the input source, this fuse will provide the following
functions:
IEC/EN/UL60950 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
•
•
Isolate the faulty DC/DC converter 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.
On-board DC-DC converters are defined as component
power supplies. As components they cannot fully comply
with the provisions of any Safety requirements without
“Conditions of Acceptability”. 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 Directives for the final
product.
The galvanic isolation is verified in an electric strength test.
The test voltage (Viso) between input and output is
1500 Vdc or 2250 Vdc for 60 seconds (refer to product
specification).
Leakage current is less than 1 μA at nominal input voltage.
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.
Component power supplies for general use should comply
with the requirements in IEC60950, EN60950 and
UL60950 “Safety of information technology equipment”.
48 and 60 V DC systems
There are other more product related standards, e.g.
IEEE802.3af “Ethernet LAN/MAN Data terminal equipment
power”, and ETS300132-2 “Power supply interface at the
input to telecommunications equipment; part 2: DC”, but
all of these standards are based on IEC/EN/UL60950 with
regards to safety.
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.
Ericsson Power Modules DC/DC converters and DC/DC
regulators are UL60950 recognized and certified in
accordance with EN60950.
If the input power source circuit is a DC power system, the
source may be treated as a TNV2 circuit and testing has
demonstrated compliance with SELV limits and isolation
requirements equivalent to Basic Insulation in accordance
with IEC/EN/UL60950.
The flammability rating for the board meets requirements
for V-0 class material according to IEC 60695-11-10.
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
circuit (AC mains) in accordance with IEC/EN/UL60950.
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.

Stress in excess of Absolute Maximum Ratings may cause permanent damage. Absolute Maximum Ratings, sometimes referred to as no destruction limits, are
normally tested with one parameter at a time exceeding the limits of Output data or Electrical Characteristics. If exposed to stress above these limits, function and
performance may degrade in an unspecified manner.

Layout recommendation
The radiated EMI performance of the DC/DC converter will
depend on the users PCB layout and ground layer design.
It is also important to consider the stand-off of the DC/DC
converter.
EMI without filter
If a ground layer is used, it should be connected to the output
of the DC/DC converter and the equipment ground or
chassis.
External filter (class B)
Required external input filter in order to meet class B in
EN 55022, CISPR 22 and FCC part 15J.
A ground layer will increase the stray capacitance in the PCB
and improve the high frequency EMC performance.

External Decoupling Capacitors
When powering loads with significant dynamic current
Operating information
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.
Input Voltage
The input voltage range of the DC/DC converters is especially
adapted to meet the requirements of non-battery backup -
48 V systems.
At input voltages exceeding 48 V, the power loss will be
higher than at normal input voltage and Tref must be limited to
absolute max +125°C.
Turn-off Input Voltage
It is equally important to use low resistance and low
inductance PCB layouts and cabling.
The absolute maximum value of output capacitance is
The DC/DC converters monitor the input voltage and will turn
on and turn off at predetermined levels.
The minimum hysteresis between on and off input
voltage is 1.0 V.
6000 μF.
For further information please contact your local Ericsson
Power Modules representative.
Remote Control (RC)
The products are fitted with a
remote control function referenced
to the primary negative input
connection (- In), with positive logic
option available. The RC function
allows the product 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 + In.
Parallel Operation
With the same input voltage and a output contact/trace
resistance of 1 mΩ or higher, the converters may be
paralleled for redundancy if the total current is equal to or less
than n × 0.95 × IO max.
For best result, trace resistance and module cooling must be
symmetrical. At this condition, the modules current share
within 5% at the maximum load.
No external components are required for parallel operation or
load sharing.
The maximum required sink current is less than 1 mA. When
the RC pin is left open, the voltage generated on the RC pin is
10 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 DC/DC 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 0.8 V. The DC/DC converter will restart
automatically when this connection is opened. Design note 21
explains more in detail about the RC pin.
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. Minimum recommended external input
capacitance is 100 μF. The performance in some applications
can be enhanced by addition of external capacitance as
described under External Decoupling Capacitors.
Over Temperature Protection (OTP)
The dc/dc converters are protected from thermal overload by
an internal over temperature shutdown circuit.
When Tref as defined in thermal consideration section
exceeds 125°C the DC/DC converter will shut down. The
DC/DC converter will make continuous attempts to start up
(non-latching mode) and resume normal operation
automatically when the temperature has dropped below the
temperature threshold.

Over Voltage Protection (OVP)
The DC/DC converters have over voltage protection that will
shut down the DC/DC converter in over voltage conditions.
The DC/DC converter will make continuous attempts to start
up (non-latching mode) and resume normal operation
automatically after removal of the over voltage condition.
The output voltage depends on the input voltage. The internal
OVP circuit detects the input voltage and is activated at an
input voltage threshold between the maximum and absolute
maximum level.
Over Current Protection (OCP)
The DC/DC converters include current limiting circuitry for
protection at continuous overload.
The DC/DC converters will go into hiccup mode for output
currents in excess of max output current (max IO). The output
will go through repeated cycles of shut-down and restart with
a duty cycle of 7 ms on and 21 ms off. During the 7 ms on
and a load of 3 mΩ the output current will reach
approximately 190 A. The DC/DC converter will resume
normal operation after removal of the overload. The load
distribution should be designed for the maximum output short
circuit current specified.

Thermal Consideration
Definition of reference temperature (Tref
)
General
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.
The DC/DC 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 DC/DC converter. Increased airflow
enhances the cooling of the DC/DC converter.
Tref is defined by the design and used to guarantee safety
margins, proper operation and high reliability of the module.
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 = 48 V.
The DC/DC converter is tested on a 254 x 254 mm,
35 μm (1 oz), 16-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 position P1. The temperature
should not exceed the max value 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 +100°C.

detailed information.

Soldering Information — Through Hole Mounting
The product is intended for manual or wave soldering. When
wave soldering is used, the temperature on the pins is
specified to maximum 270°C for maximum 10 seconds.
A maximum preheat rate of 4°C/s and a temperature of max
+150°C is suggested. When soldering by hand, care should
be taken to avoid direct contact between the hot soldering
iron tip and the pins for more than a few seconds in order to
prevent overheating.
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.
