Reliability
The Mean Time Between Failure (MTBF) is calculated at
full output power and an operating ambient temperature
(TA) of +40°C. Different methods could be used to calculate
the predicted MTBF and failure rate which may give
different results. Ericsson Power Modules currently uses
two different methods, Ericsson failure rate data system
DependTool and Telcordia SR332.
Predicted MTBF for the series is:
- 1.71million hours according to Telcordia SR332,
issue 1, Black box technique.
The Ericsson failure rate data system is based on field
tracking data. The data corresponds to actual failure rates
of components used in Information Technology and
Telecom (IT&T) equipment in temperature controlled
environments(TA = -5...+65°C). Telcordia SR332 is a
commonly used standard method intended for reliability
calculations in IT&T 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 AB
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)
Quality Statement
The products are designed and manufactured in an
industrial environment where quality systems and methods
like ISO 9000, 6σ (sigma), and SPC are intensively in use
to boost the continuous improvements strategy. Infant
mortality or early failures in the products are screened out
and they are subjected to an ATE-based final test.
Conservative design rules, design reviews and product
qualifications, plus the high competence of an engaged
work force, contribute to the high quality of our products.
Warranty
Warranty period and conditions are defined in
Ericsson AB General Terms and Conditions of Sale.
Limitation of Liability
Ericsson AB 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

Safety Specification
General information
Ericsson AB DC/DC converters and DC/DC regulators are
designed in accordance with safety standards
IEC/EN/UL60950, Safety of Information Technol ogy
Equipment.
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
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.
Component power supplies for general use should comply
with the requirements in IEC60950, EN60950 and
UL60950 “Safety of information technology equi pment”.
There are other more product related standards, e.g.
EC61204-7 “Safety standard for power supplies",
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.
Ericsson AB DC/DC converters and DC/DC regulators are
UL60950 recognized and certified in accordance with
EN60950.
The flammability rating for all construction parts of the
products 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.
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.
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:
• 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.
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 refer to
Absolute maximum ratings).
Leakage current is less than 100 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.
48 and 60 V DC systems
If the input voltage to Ericsson AB 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 TNV2 circuit and testing has
demonstrated compliance with SELV limits and isolation
requirements equivalent to Basic Insulation 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 recommendations
The radiated EMI performance of the Product will depend on
the PCB layout and ground layer design. It is also important to
consider the stand-off of the product. If a ground layer is used,
it should be connected to the output of the product and the
equipment ground or chassis.
A ground layer will increase the stray capacitance in the PCB
and improve the high frequency EMC performance.

Operating information
Input Voltage
The input voltage range 18 to 72Vdc 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 72 V, the power loss will be higher
than at normal input voltage. Precaution must be taken to
keep TP1 below +95°C. The absolute maximum continuous
input voltage is 80 Vdc.
Turn-off Input Voltage
The products 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 1V. The input voltage supply must have low
impedance to prevent the risk of input oscillation, poor supply
can also cause shutdown-bouncing.
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 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.
The maximum required sink current is 1 mA. When the RC pin
is left open, the voltage generated on the RC pin is
4.5 – 5.5 V.
The standard product is provided with “negative logic” remote
control and will be off until the RC pin is connected to the -In.
To turn on the product the voltage between RC pin and -In
should be less than 1V.
To turn off the converter the RC pin should be left open, or
connected to a voltage higher than 4 V referenced to -In. In
situations where it is desired to have the product to power up
automatically without the need for control signals or a switch,
the RC pin can be wired directly to -In.
The second option is “positive logic” remote control, which can
be ordered by adding the suffix “P” to the end of the part
number.
When the RC pin is left open, the product starts up
automatically when the input voltage is applied.
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 product 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 performance in some applications can be enhanced by
addition of external capacitance as described in External
Decoupling Capacitors.
If the input voltage source contains significant inductance, the
addition of a low ESR 47 µF capacitor across the input of the
converter will ensure stable operation in all conditions.
External Decoupling Capacitors
The products have been designed to operate with a minimum
capacitance connected to their output.
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. If significant inductance
are within the load distribution, >50% of the stated “Minimum
Output Capacitance” shall be located at the module’s output.
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. Ericsson Power
Modules guarantee stable operation with a verified ESR value
of >10 mΩ across the output connections.

Operating information continued
Output Voltage Adjust (Vadj)
The products 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 must be kept below the threshold of the over voltage
protection, (OVP) to prevent the product from entering OVP.
At increased output voltages the maximum power rating of the
product 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 +Out 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 –Out pin.
Over Temperature Protection (OTP)
The converters are protected from thermal overload by an
internal over temperature shutdown circuit.
When TP1 as defined in thermal consideration section reach
exceeds 105°C the 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 hot-spot temperature has dropped
10°C below the temperature threshold.
Over Voltage Protection (OVP)
The converters have output over voltage protection that will
prevent output voltage to exceed the specified value in
technical specification.
The converter will limit the outputvoltage to the maximum
level. Converters will resume normal operation automatically
after removal of the over voltage condition.
Over Current Protection (OCP)
The converters include current limiting circuitry for protection
at continuous overload.
The output voltage will decrease towards zero for output
currents in excess of max output current (max IO).
After a time period exceeding 10 ms in OCP converters will
enter hiccupmode to reduce average output power.
During short-circuit condition module temperature will increase
rapidly and OTP function may be activated.
Module will not resume from hiccup shutdown period unless
the temperature drops below the OTP re-activation
temperature.
The converter will resume normal operation after removal of
the overload. The load distribution should be designed for the
maximum output short circuit current specified.
Pre-bias Start-up
The product has a Pre-bias start up functionality and will not
sink current during start up or RC-off if a pre-bias source with
less than 75% of Vo is present at the output terminals.
Precaution must be taken that reverse current might be
present if Vi is disabled. Without Vi a small current will
discharge external capacitors.
NB! Feeding Vo from external power supply for test purpose
might without Vi cause high reverse current.

Thermal Consideration
General
The products are designed to operate in different thermal
environments and sufficient cooling must be provided to
ensure reliable operation.
For products mounted on a PCB without a heat sink attached,
cooling is achieved mainly by conduction, from the pins to the
host board, and convection, which is dependant on the airflow
across the product. Increased airflow enhances the cooling of
the product. 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
VI = 53 V.
The product 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 608 x 203 mm.
Proper cooling of the product can be verified by measuring the
temperature at position P1. The temperature at this position
should not exceed the max values provided in the table below.
The number of points may vary with different thermal design
and topology.
See Design Note 019 for further information.

Open frame
Definition of reference temperature TP1
The reference temperature is used to monitor the temperature
limits of the product. Temperatures above maximum TP1,
meassured at the reference point P1 are not allowed and may
cause degradation or permanent damage to the product. TP1 is
also used to define the temperature range for normal operating
conditions. TP1 is defined by the design and used to guarantee
safety margins, proper operation and high reliability ot the
product.

Soldering Information - Surface Mounting
The surface mount product is intended for forced convection
or vapor phase reflow soldering in SnPb or Pb-free processes.
The reflow profile should be optimised to avoid excessive
heating of the product. It is recommended to have a
sufficiently extended preheat time to ensure an even
temperature across the host PCB and it is also recommended
to minimize the time in reflow.
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, since cleaning residues may
affect long time reliability and isolation voltage.
Minimum Pin Temperature Recommendations
Pin number 8 is chosen as reference location for the minimum
pin temperature recommendation since this will likely be the
coolest solder joint during the reflow process.
SnPb solder processes
For SnPb solder processes, a pin temperature (T
PIN
) in excess
of the solder melting temperature, (T
L
, 183°C for Sn63Pb37)
for more than 30 seconds and a peak temperature of 210°C is
recommended to ensure a reliable solder joint.
Lead-free (Pb-free) solder processes
For Pb-free solder processes, a pin temperature (T
PIN
) in
excess of the solder melting temperature (T
L
, 217 to 221°C for
SnAgCu solder alloys) for more than 30 seconds and a peak
temperature of 235°C on all solder joints is recommended to
ensure a reliable solder joint.
