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:
- 2.2 million hours according to DependTool.
- 1.05 million 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 failre 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
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

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 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 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 (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.
48 and 60 V DC systems
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.
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.

Output Voltage Adjust (see operating information)
Passive adjust
The resistor value for an adjusted output voltage is calculated by
using the following equations:
Output Voltage Adjust Upwards, Increase:
Radj= [(Vo(100+Δ%)/(1.225Δ%)-(100+2Δ%)/Δ%) kΩ
Eg Increase 5% =>Vout = 1.89 Vdc
1.8(100+5)/(1.225x5)-(100+2x5)/5 = 8.8 kΩ
Output Voltage Adjust Downwards, Decrease:
Radj= (100 / Δ%-2) kΩ
Eg Decrease 5% =>Vout = 1.71 Vdc
(100/5-2)= 18 kΩ

Passive adjust
The resistor value for an adjusted output voltage is calculated by
using the following equations:
Output Voltage Adjust Upwards, Increase:
Radj= [(Vo(100+Δ%)/(1.225Δ%)-(100+2Δ%)/Δ%) kΩ
Eg Increase 5% =>Vout = 1.89 Vdc
1.8(100+5)/(1.225x5)-(100+2x5)/5 = 8.8 kΩ
Output Voltage Adjust Downwards, Decrease:
Radj= (100 / Δ%-2) kΩ
Eg Decrease 5% =>Vout = 1.71 Vdc
(100/5-2)= 18 kΩ

Output Voltage Adjust Downwards, Decrease:
Radj= (100 / Δ%-2) kΩ
Eg Decrease 2% =>Vout = 11.76 Vdc

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.
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 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 +100°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 1V.
Remote Control (RC)
The products are fitted with a
remote control function referenced
to the primary negative input
connection (- In), with negative and
positive lo
g
ic options available. The
RC function allows the converter to
be turned on/off by an external
device like a semiconductor or
mechanical switch.
The maximum required sink current is 1 mA. When the RC pin
is left open, the voltage generated on the RC pin is
3.0 — 6.5 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.
External Decoupling Capacitors
When powering loads with significant dynamic current
requirements, the voltage regulation at the point of load can
be improved b
y
addition of decouplin
g
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 mΩ across the output connections.
For further information please contact your local Ericsson
Power Modules 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
Parallel Operation
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.
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 an
internal over temperature shutdown circuit. When the
baseplate or case temperature exceeds 110°C the converter
will shut down immediately(latching). The converter can be
restarted by cycling the input voltage or using the remote
control function.
Over Voltage Protection (OVP)
The converters have output over voltage protection that will
shut down the converter in over voltage conditions. The
converter can be restarted by cycling the input voltage or
using the remote control function.
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). 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.
Thermal Consideration
General
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.
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), 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 positions P1. 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 +100°C.
See Design Note 019 for further information.

Thermal Consideration continued
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 89.5 % = 0.895
2. Find the thermal resistance (Rth) in the Thermal Resistance
graph found in the Output section for each model.
Calculate the temperature increase (ΔT).
ΔT = Rth x Pd
3. Max allowed ambient temperature is:
Max Tref - ΔT.
E.g PKL4118B PIT at 2m/s:
1. (( ) - 1) × 144 W = 25.0 W
2. 25.0 W × 1.3°C/W = 32.5°C
3. 110 °C — 32.5°C = max ambient temperature is 77.5°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 PKL series DC/DC converters are intended for through
hole mounting in a PCB. When wave soldering is used max
temperature on the pins is specified to 260°C for 10 seconds.
Maximum preheat rate of 4°C/s and temperature of max
150°C is suggested. When hand 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.
No-clean 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.
