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 in other applications other
than lead in solder, lead in high melting temperature type
solder, lead in glass of electronics components, lead in
electronic ceramic parts and lead as an alloying element in
copper containing up to 4% lead by weight, mercury,
hexavalent chromium, PBB and PBDE and of 0.01% by
weight in homogeneous materials for cadmium.
Exemptions in the RoHS directive utilized in the products:
- Lead as an alloying element in copper alloy containing
up to 4% lead by weight (used in connection pins
made of Brass)
- 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 in solder for servers, storage and storage array
systems, network infrastructure equipment for
switching, signaling, transmission as well as network
management for telecommunication
(Note: the products are manufactured in lead-free
soldering processes and the lead present in the solder
is only located in the terminal plating finishes on some
components)
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.

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.

Bottom trace: load current (10 A/div.).
Time scale: {0.1 ms/div.}.
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:
Radj= 5.11((5(100+Δ%))/1.225Δ%-(100+2Δ%)/Δ%) kOhm
Eg Increase 4% =>Vout =5.2 Vdc
5.11(5(100+4)/1.225x4-(100+2x4)/4 = 404 kOhm0
Output Voltage Adjust Downwards, Decrease:
Radj= 5.11(100/Δ%-2) kOhm
Eg Decrease 2% =>Vout = 4.90 Vdc
5.11(100/2-2)= 245 kOhm

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
round la
er 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

Operating information
Input Voltage Output Voltage Adjust (Vadj)
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
+110°C. The absolute maximum continuous input voltage is
80Vdc.
Turn-off Input Voltage
The PKM 4000CSeries 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 1 V.
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 range.
A
lso 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.
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 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 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. Remote Sense
The standard converter is provided with “negative logic”
remote control and the converter will be off until the RC pin is
connected to the - In. To turn on the converter the voltage
between RC pin and - In should be less than 1 V. To turn off
the converter the RC pin should be left open, or connected to
a voltage higher than 2 V referenced to - In. In situations
where it is desired to have the converter 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. 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 0.8 V. The converter will restart automatically when
this connection is opened.
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 carr
ver
little current and do not need a lar
e
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 voltage and
the voltage at the output pins. The output voltage 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.

Operating information, cont.
Input And Output Impedance 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.
Over Temperature Protection (OTP)
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 designed to be completely 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.
Maximum Capacitive Load
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 tri
point (120 °C) for the OTP circuit
the converter will cut down output power. The converter will
go into hiccup mode until safe operational temperature is
restored.
Over Voltage Protection (OVP)
The PKM 4000CSeries DC/DC converters include output
overvoltage protection. In the event of an overvoltage
condition due to malfunction in the voltage monitoring
circuits, the converter's PWM will automatically dictate
minimum duty-cycle thus reducing the output voltage to a
minimum.
Over Current Protection (OCP)
When powering loads with significant dynamic current
requirements, the voltage regulation at the load can be
improved by addition of decoupling capacitance 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. These ceramic
capacitors will handle short duration high-frequency
components of dynamic load changes. In addition, higher
values of electrolytic capacitors should be used to handle the
mid-frequency components. It is equally important to use
good design practise when configuring the DC distribution
system.
Low resistance and low inductance Pcb layouts and cabling
should be used. Remember that when using remote sensing,
all resistance, inductance and capacitance of the distribution
system is within the feedback loop of the converter. This can
affect on the converters compensation and the resulting
stability and dynamic response performance. As a “rule of
thumb”, 100μF/A of output current can be used without any
additional analysis. For example with a 25A converter, values
of decoupling capacitance up to 2500 μF can be used without
regard to stability. With larger values of capacitance, the load
transient recovery time can exceed the specified value. As
much of the capacitance as possible should be outside the
remote sensing loop and close to the load. The absolute
maximum value of output capacitance is 10000 μF. For values
larger than this, please contact your local Ericsson Power
Modules representative.
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 Ambient Temperature Calculation
The PKM 4000Cseries DC/DC converters are designed to
operate in a variety of thermal environments, however
sufficient cooling should be provided to help ensure reliable
operation. Heat is removed by conduction, convection and
radiation to the surrounding environment. Increased airflow
enhances the heat transfer via convection. The available load
current vs. ambient air temperature and airflow at Vin =53 V
for each model is according to the information given under
the output section. The test is done in a wind tunnel with a
cross section of 305 x 305 mm, the DC/DC converter
vertically mounted on a 16 layer Pcb with a size of 254 x 254
mm, each layer with 35 μm (1 oz) copper. Proper cooling can
be verified b

g
the temperature of selected devices.
Peak temperature can occur at positions P1 - P4. The
temperature at these positions should not exceed the
recommended max values.
Note that the max value is the absolute maximum rating
(non destruction) and that the electrical Output data is
guaranteed up to Tref +90°C.
Position Device Designation max value
P1 Pcb Tref 110º C
P2 Mosfet Tsurface 120º C
P3 Mosfet Tsurface 120º C
P4 Transformer Tsurface 130º C
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 90 % = 0.90
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 PKM 4110C PINB at 1m/s:
1. (( ) - 1) × 115 W = 18.3 W
2. 18.3 W × 2.3°C/W = 42°C
3. 110 °C - 42°C = max ambient temperature is 68°C
The real temperature will be dependent on several factors, like
Pcb size and type, direction of airflow, air turbulence etc.
It is recommended to verify the temperature by testing.

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 260 °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.
