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 two different methods,
Ericsson failure rate data system DependTool and
Telcordia SR332.
Predicted MTBF for the series is:
- 2.7 million hours according to DependTool.
- 1.4 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 failure rates
of components used in ICT equipment in temperature
controlled environments (TA = -5...+65°C).
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 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.

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.
Output ripple and noise
Output ripple and noise measured according to figure below.

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 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 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 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 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 power source and the load will
interact with the impedance of the DC/DC converter. It is
most important to have a low characteristic impedance, both
at the input and output, as the converters have a low energy
storage capability. The PKM 4000CSeries DC/DC converters
have been desi
g
ned to be completel
y
stable without the need
for external capacitors on the input or the output circuits. The
performance in some applications can be enhanced by
addition of external capacitance as described under
maximum capacitive load. If the distribution of the input
voltage source to the converter contains significant
inductance, the addition of a 100µF capacitor across the
input of the converter will help insure stability. This capacitor
is not required when powering the DC/DC converter from a
low impedance source with short, low inductance, input
power leads.
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.

Power Modules representative.
Output Voltage Adjust (V
adj
)
All PKM 4000CSeries 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 offset) must be kept below
the maximum output adjust ran
g
e. Also note that at increased
output voltages the maximum power rating of the converter
remains the same, and the output current capability will
decrease correspondingly.
To decrease the output voltage the resistor should be
connected between Vadj pin and —Sense pin. To increase the
voltage the resistor should be connected between Vadj pin
and +Sense pin. The resistor value of the Output voltage
adjust function is according to information given under the
output section.

Operating information continued
Parallel Operation
The PKM 4000CSeries DC/DC converters can be paralleled
for redundancy if external o-ring diodes are used in series
with the outputs. It is not recommended to parallel the PKM
4000C Series DC/DC converters for increased power without
using external current sharing circuits.
See Design Note 006 for detailed information.
Remote Sense
All PKM 4000CSeries DC/DC converters have remote sense
that can be used to compensate for moderate amounts of
resistance in the distribution system and allow for voltage
regulation at the load or other selected point. The remote
sense lines will carry very little current and do not need a
large cross sectional area. However, the sense lines on the
Pcb should be located close to a ground trace or ground
plane. In a discrete wiring situation, the use of twisted pair
wires or other technique to reduce noise susceptibility is
highly recommended. The remote sense circuitry will
compensate for up to 10% voltage drop between the sense
volta
g
e and the volta
g
e at the output pins. The output volta
g
e
and the remote sense voltage offset must be less than the
minimum over voltage trip point. If the remote sense is not
needed the —Sense should be connected to —Out and +Sense
should be connected to +Out.
Over Temperature Protection (OTP)
The PKM 4000CSeries DC/DC converters are protected from
thermal overload by an internal over temperature shutdown
circuit. When the Pcb temperature (TC reference point)
exceeds the temperature trig point (~130 °C) the OTP circuit
will cut down output power. The converter will stop until safe
operating temperature is restored. Hysteresis between OTP
trig point and restart is approx 15 °C. Time between OTP and
restart is dependant on cooling of DC/DC converter.
Over Voltage Protection (OVP)
The PKM 4000CSeries DC/DC converters have output
overvoltage protection. In the event of an output overvoltage
condition, the converter will shut down immediately. The
converter make continous attempts to start up (non-latching
mode) and resume normal operation automatically.
Over Current Protection (OCP)
The PKM 4000CSeries DC/DC converters include current
limiting circuitry that allows them to withstand continuous
overloads or short circuit conditions on the output. The
output voltage will decrease towards zero for output currents
in excess of max output current (Iomax).
The converter will resume normal operation after removal of
the overload. The load distribution system should be
designed to carry 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 and P2. 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. 87.5% = 0.875
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. PKM 4118HC PI at 2m/s:
1. (( ) - 1) × 150 W = 30.72 W
2. 30.72 W × 2.8°C/W = 86.0°C
3. 125 °C – 86.0°C = max ambient temperature is 39.0°C
The actual temperature will be dependent on several factors
such as the PCB size, number of layers and direction of
airflow.
