Reliability
The Mean Time Between Failure (MTBF) is calculated at
full output power and an operating ambient temperature
(T
A
) 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.
Predicted MTBF for the series is:
- 1.46 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)
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
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.
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 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
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 equipment”.
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.
Ericsson Power Modules 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 (V
iso
) 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.
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 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 36 to 75 Vdc 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 T
P1
must be limited to
absolute max +125°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 1 V.
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
3.5 – 6.0 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 product. It is important that
the input source has low characteristic impedance. The
products 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 22 - 100 µF capacitor across the input of the
product will ensure stable operation. The capacitor is not
required when powering the product from an input source with
an inductance below 10 µH. The minimum required
capacitance value depends on the output power and the input
voltage. The higher output power the higher input capacitance
is needed. Approximately doubled capacitance value is
required for a 24 V input voltage source compared to a 48V
input voltage source.
External Decoupling Capacitors
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. 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
mΩ across the output connections.
For further information please contact your local Ericsson
Power Modules representative.
Output Voltage Adjust (V
adj
)
The products have an Output Voltage Adjust pin (V
adj
). 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 product from shutting down. 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 V
adj
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 V
adj
pin and –Sense pin.

Operating information continued
Parallel Operation
Two products may be paralleled for redundancy if the total
power is equal or less than P
O
max. It is not recommended to
parallel the products without using external current sharing
circuits.
See Design Note 006 for detailed information.
Remote Sense
The products 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 products are protected from thermal overload by an
internal over temperature shutdown circuit.
When T
P1
as defined in thermal consideration section exceeds
135°C the product will shut down immediately (latching). The
product can be restarted by cycling the input voltage or using
the remote control function.
Over Voltage Protection (OVP)
The products have latching output over voltage protection that
immediately will shut down the product in over voltage
conditions. The product can be restarted by cycling the input
voltage or using the remote control function.
Over Current Protection (OCP)
The products 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
I
O
). The product 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
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
V
I
= 53 V.
The product 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 608 x 203 mm.

Proper cooling of the product 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. The number of points may vary with different
thermal design and topology.
See Design Note 019 for further information.

Definition of reference temperature T
P1
The reference temperature is used to monitor the temperature
limits of the product. Temperatures above maximum T
P1
,
meassured at the reference point P1 are not allowed and may
cause degradation or permanent damage to the product. T
P1
is
also used to define the temperature range for normal operating
conditions. T
P1
is defined by the design and used to guarantee
safety margins, proper operation and high reliability ot the
product.
Ambient Temperature Calculation
For products with base plate the maximum allowed ambient
temperature can be calculated by using the thermal resistance.
1. The power loss is calculated by using the formula
((1/η) - 1) × output power = power losses (Pd).
η = efficiency of product. E.g. 89.5% = 0.895
2. Find the thermal resistance (Rth) in the Thermal Resistance
graph found in the Output section for each model. Note that
the thermal resistance can be significantly reduced if a
heat sink is mounted on the top of the base plate.
Calculate the temperature increase (∆T).
∆T = Rth x Pd
3. Max allowed ambient temperature is:
Max T
P1
- ∆T.
E.g. PKJ 4110E PIHS at 1 m/s:
1. (( ) - 1) × 100 W = 13 W
2. 13 W × 3.8°C/W = 50°C
3. 125 °C - 50°C = max ambient temperature is 75°C
The actual temperature will be dependent on several factors
such as the PCB size, number of layers and direction of
airflow.

Soldering Information — Through hole mounting
The product is intended for through hole mounting in a PCB.
When wave soldering is used, the temperature on the pins is
specified to maximum 270 °C for maximum 10 seconds.
Maximum preheat rate of 4 °C/s and temperature of max
150 °C is suggested. When hands soldering 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 (NC) flux is recommended to avoid entrapment of
cleaning fluids in cavities inside of the DC/DC power module.
The residues may affect long time reliability and isolation
voltage.
