Reliability
-
Lead as an alloying element in copper alloy containing
up to 4% lead by weight (used in connection pins
made of Brass)
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.
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.
Predicted MTBF for the series is:
-
1.82 million hours according to Telcordia SR332,
issue 1, Black box technique.
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.
The Ericsson failure rate data system is based on field
tracking data. The data corresponds to actual failure 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.
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).
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.

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 100 µA at nominal input
voltage.
24 V DC systems
Component power supplies for general use should comply
with the requirements in IEC60950, EN60950 and
UL60950 “Safety of information technology equipment”.
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.
There are other more product related standards, e.g.
EC61204-7 “Safety standard for power supplies",
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.
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.
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.

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 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.
EMI without filter
If a ground layer is used, it should be connected to the output
of the DC/DC converter and the equipment ground or
chassis.
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.

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.For loosely regulated
DC/DC converters, such as PKM-B intermediate bus con-
verters, there is no limit on the value of output capacitance
that may be used. The user should be aware, however, that
large values of capacitance will affect the ramp-up time of the
DC/DC converter output voltage during start-up.
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 Tref must be limited to
absolute max 115°C. The absolute maximum continuous input
voltage is 80 Vdc.
Turn-off Input Voltage
Parallel Operation
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 1 V.
The PKM 4000B Series DC/DC converters can be connected
in parallel with a common input. Paralleling is accomplished
by connecting the output voltage pins and input pins directly.
No external components are necessary. Up to 90% of max
output current can be used from each module. Layout
considerations should be made to avoid unbalanced current
sharing. For more details on paralleling, please consult your
local Ericsson Power Modules representative.
Remote Control (RC)
The products are fitted with a
remote control function referenced
to the primary negative input
connection (- In), and positive logic
options available. The RC function
allows the DC/DC 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 0.2 mA. When the RC
pin is left open, the voltage generated on the RC pin is
max 10 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 DC/DC converter will turn on
when the RC pin is left 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 DC/DC converter will restart automatically
when this connection is opened.

Output Current (A)
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 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
330 μF capacitor across the input of the DC/DC converter will
ensure stable operation.
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,

Over Temperature Protection (OTP)
The DC/DC converters are protected from thermal overload
by an internal over temperature shutdown circuit.
When Tref as defined in thermal consideration section
exceeds 135°C the DC/DC converter will shut down. The
DC/DC converter will make continuous attempts to start up
(non latching mode) We provide an optional variant of the
product with a latching OTP. Add suffix “LP” to the standard
product code to order the latching version. The latching OTP
version has a latching OVP as well.
If the OTP/OVP is latched the module can be put in operation
either by switching OFF and ON the input voltage or drive
OFF and ON the RC (Remote Control) pin.
Over Voltage Protection (OVP)
The DC/DC converters have output over voltage protection
that will shut down the DC/DC converter in over voltage
conditions. The DC/DC converter will make continuous
attempts to start up (non-latching mode) and resume normal
operation automatically after removal of the over voltage
condition.
Add suffix “LP” to the standard product code to order the
latching version. The latching OVP version has a latching OTP
as well.
If the OTP/OVP is latched the module can be put in operation
either by switching OFF and ON the input voltage or drive
OFF and ON the RC (Remote Control) pin.
Over Current Protection (OCP)
The 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 DC/DC
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
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 reliability of the module.
General
The product is designed to operate in various 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. The size and copper
thickness of the host board will have impact on the
Conduction cooling. Convection cooling is dependant on the
airflow across the DC/DC converter. Increased airflow
enhances the cooling of the DC/DC converter.
Ambient Temperature Calculation
By using the thermal resistance the estimated maximum
allowed ambient temperature can be calculated.
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.
1. The power loss is calculated by using the formula
((1/η) - 1) × output power = power losses (Pd).
η = efficiency of converter. E.g 96 % = 0.96
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.
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
Proper cooling of the DC/DC converter can be verified by
measuring the temperature at reference point. The
temperature at these positions should not exceed the max
values provided in the table below.
3. Max allowed ambient temperature is:
Ta=Max Tref - ΔT.
E.g. PKM4204B PI at 53Vin 20Aout 1.5 m/s
1. ((1/0.96) — 1) x 240W = 10 W

2. 10 W x 3.8o C = 38o C
3. 130o C — 38o C = max ambient temperature is 92o 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 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.
The residues may affect long time reliability and isolation
voltage.
