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)
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 one method, Telcordia
SR332.
-
-
The exemption for lead in solder for servers, storage and
storage array systems, network infrastructure equipment
for switching, signaling, transmission as well as network
management for telecommunication is only utilized in
surface mount products intended for end-users’ leaded
SnPb Eutectic soldering processes. (See ordering
information table).
Predicted MTBF for the series is:
-
7.2 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.
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
Power Modules General Terms and Conditions of Sale.
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).

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 Ericsson Power Modules 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 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.
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.

Output Voltage Adjust (see operating information)
Passive trim
The resistor value for an adjusted output voltage is calculated by using
the following equations:
Output Voltage Adjust Upwards, Increase:
Rou= 0.684 x (2.38 — Vo) / ( Vo - Voi) kΩ
Eg Increase 4% =>V0 =2.20 Vdc
0.684 x (2.38 — 2.20) / ( 2.20 — 2.12) = 1.54 kΩ
Output Voltage Adjust Downwards, Decrease:
Rod= 2.751 x ( Voi — Vo) / (Vo —1.75) kΩ
Eg Decrease 2% =>V0 = 2.08Vdc
2.751 x ( 2.12 — 2.08) / (2.08 —1.75)= 0.33 kΩ

Passive trim
The resistor value for an adjusted output voltage is calculated by using
the following equations:
Output Voltage Adjust Upwards, Increase:

E.g. Increase 4% =>Vout = 3.43 Vdc
0.495 × (3.93 — 3.43)/( 3.43 — 3.3) = 1.9 kΩ
Output Voltage Adjust Downwards, Decrease:

Output Voltage Adjust (see operating information)
Passive trim
The resistor value for an adjusted output voltage is calculated by
using the following equations:
To adjust the output voltage downwards, a resistor is connected
between pins 8 and 9. The output voltage decreases when the
connected resistance value increases. The resistance value is given by
the equation:
To adjust the output voltage upwards, a resistor is connected
between pins 8 and 18. Pins 8 and 9 have to be shorted. The output
voltage increases when the resistance decreases. The resistance
value is given by the equation:
Rod= 2.284*(12-Vo)/(Vo-9.52), (kOhm), Vo is the desired output voltage.
Rou= 0.566*(15-Vo)/(Vo-12), (kOhm); Vo is the desired output
voltage. Over 13.8V output voltage the input voltage range is limited
to 38…65 V.

Layout recommendation
The radiated EMI performance of the DC/DC converter will
depend on the PCB layout and ground layer design.
It is also important to consider the stand-off of the DC/DC
converter.
If a ground layer is used, it should be connected to the output
of the DC/DC converter and the equipment ground or
chassis.
EMI without filter
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.

applications can be enhanced by addition of external
Operating information
capacitance as described under maximum capacitive load. If
the input voltage source contains significant inductance, the
addition of a 10 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.
Input Voltage
The input voltage range 38…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…-57.0 V and —50.0…-72 V respectively.
At input voltages exceeding 72 V, the power loss will be
higher than at normal input voltage and Tref must be limited to
absolute max +85°C. The absolute maximum continuous
input voltage is 75Vdc.
External Decoupling Capacitors
When powering loads with significant dynamic current
requirements, the voltage regulation at the load can be
improved by addition of decoupling capacitors at the load.
The most effective technique is to locate low ESR ceramic
capacitors as close to the load as possible, using several
capacitors to lower the effective ESR. The ceramic capacitors
will handle high-frequency dynamic load changes while
electrolytic capacitors should be used to handle low
frequency dynamic load changes.
Turn-off Input Voltage
The converters monitor the input voltage and will turn on and
turn off at predetermined levels.
To increase VIon a resistor should be connected between pin
11 and 17. The resistance is given by the following equation:
Rset(up) = 100(X - Von)/(Von - VIon) kΩ
It is equally important to use low resistance and low
inductance PCB layouts and cabling.
To decrease VIon a resistor should be connected between pin
10 and 11. The resistance is given by the following equation:
Rset(down) = 370(Von - Y)/(VIon - Von) kΩ
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 absolute maximum value of output capacitance is
5 000 μF. For further information please contact your local
Ericsson Power Modules representative.

All PKR 4000 Series 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.
At increased output voltages the maximum power rating of
the converter remains the same, and the max output current
must be decreased correspondingly.
Remote Control (RC)
The products are fitted with a
remote control function referenced
to the primary negative input
connection (- In), with positive
logic. 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 + In.
The output voltage can be increased or decreased by means
of external resistors or other external circuitry. If other
circuitry is used, the slew rate has to be limited to maximum 5
V/ms. To increase the voltage a resistor should be connected
between the Vadj pin and +IN. To decrease the output voltage,
a resistor is connected between Vadj pin and NOR pin. The
resistor value of the Output voltage adjust function is
according to information given under the Output section for
the respective product.
The maximum required sink current is 0.1 mA. When the RC
pin is left open, the voltage generated on the RC pin is
<15 V. To ensure that the converter stays off the voltage must
be below 1.0V.
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 PKR 4000 Series DC/DC converters are
designed for stable operation without external capacitors
connected to the input or output. The performance in some

Thermal Consideration
Parallel Operation
General
Paralleling of several PKR 4000 converters is easily
The PKR 4000 series 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 PCB board, and convection, which is dependant on the
airflow across the converter. Increased airflow enhances the
cooling of the converter.
accomplished by direct connection of the output voltage
terminal pins. The load regulation characteristic is specifically
designed for optimal paralleling performance. Load sharing
between converters will be within ±10%. It is recommended
not to exceed PO = n x 0.9 x POmax, where POmax is the
maximum converter output power and n the number of
paralleled converters, to prevent overloading any of the
converters and thereby decreasing the reliability performance. 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 = 53V.
Over Current Protection (OCP)
The PKR 4000 Series DC/DC 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). 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.
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. The temperature
at this position 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 +85°C.

Mixed Solder Process Recommendations
Soldering Information - Surface Mounting
The surface mount version of the product is intended for
convection reflow or vapor phase reflow in SnPb or Pb-free
reflow processes.
When using products with Pb-free solder bumps and thereby
mixing Pb-free solder with SnPb paste on the host board and
reflowing at SnPb process temperatures (backwards
compatibility), special recommendations apply.
Mounting Options
The surface mount version is available in two options, SnPb
based or SnAgCu based (Pb-free) solder bumps.
An extended preheat time between +170°C and +180°C for
60 to 90s and a pin reflow temperature (TPIN) between +220°C
and +225°C for 30 to 60 s is recommended.
The SnPb solder bumps are intended for SnPb solder paste
on the host board and to be reflowed in SnPb reflow process
temperatures, typically +210 to +220°C.
The extended preheat and soak at reflow temperature will
minimize temperature gradients and maximize the wetting
and solder mixing in the final solder joints. The use of nitrogen
reflow atmosphere will further improve the solder joint quality.
The Pb-free solder bumps are intended for Pb-free solder
paste on the host board and to be reflowed in Pb-free reflow
process temperatures, typically +235 to +250°C.
Temperature
Note that recommendations for minimum and maximum pin
temperature — and maximum peak product temperature — are
different depending on mounting option, reflow process type
and if the dry packing of the products has been kept intact.

General Reflow Profile Recommendations
Time
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 to minimize the time in
reflow.
Dry Pack Information
Products intended for Pb-free reflow processes are delivered
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). The SnPb
option of this product is also delivered in dry packing.
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.
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.

Pin Temperature Recommendations
Surface Mount Assembly and Repair
Pin number 5 and 14 are chosen as reference locations for
the minimum pin (solder joint) temperature recommendations
since these will likely be the coolest solder joints during
reflow
The solder bumps of the product require particular care
during assembly since the solder bumps are hidden between
the host board and the product’s PCB. Special procedures
are required for successful rework of these products.

peak temperature of +210°C is recommended to ensure a
reliable solder joint.
system, utilizing the fiducials on the bottom side of the
product, will ensure adequate accuracy. Manual mounting of
solder bump products is not recommended.
A maximum pin temperature of +225°C should be sufficient
for most applications but depending on type of solder paste
and flux system used on the host board, up to a
recommended maximum temperature of +245°C could be
used, provided that the products are kept in a controlled
environment (dry pack handling and storage) prior to
assembly.
Note that the actual position of the pick up surface may vary
between variants within the product program and is not
necessarily in the center of the product outline.
If necessary, it is recommended to fine tune the solder print
aperture size to optimize the amount of deposited solder with
consideration to screen thickness and solder print capability.

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.
The rework system should preferably utilize a bottom side
heater and a dedicated hot air nozzle to heat the solder
bumps to reflow temperature.
The product is an open frame design with a pick up surface
on a large central component. This pick up surface can not be
used for removal with a vacuum nozzle since the component
solder joints may have melted during the removal reflow.
Maximum Product Temperature Requirements
Top of the product PCB near pin 9 or 10 are chosen as
reference locations for the maximum (peak) allowed product
temperature (TPRODUCT), since these will likely be the warmest
parts of the product during the reflow process.
In order not to damage the product and nearby components
during removal and replacement with a new product, it is
recommended to use a double wall design of the hot air
nozzle to direct the air flow only to the edges of the product,
see ‘Assembly Information’ in the mechanical drawing.
SnPb Solder Processes
For conventional SnPb solder processes, the product is
qualified for MSL 1 according to IPC/JEDEC standard
J-STD-020C (no dry pack handling or controlled environment
required)
Soldering Information — Hole Mounting
The hole mount version of the product is intended for manual
or wave soldering in plated through holes on the host board.
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 preheat temperature
of max of +150°C is suggested.
During reflow, TPRODUCT must not exceed +225 °C at any time.
If the products are handled as MSL 3 products, they can
withstand up to +260°C as in Pb-free solder processes.
Pb-free Solder Processes
For Pb-free solder processes, the product is qualified for
MSL 3 according to IPC/JEDEC standard J-STD-020C.
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.
During reflow, TPRODUCT must not exceed +260 °C at any time.
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.
