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 Telcordia
SR332.
Predicted MTBF for the series is:
- 4.02 million hours according to Telcordia SR332, issue
1, Black box technique.
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)
The exemption for lead in solder for servers, storage and
storage array systems, network infrastructure equipment
for switching, signaling, transmission as well as network
management for telecommunication is only utilized in
surface mount products intended for end-users’ leaded
SnPb Eutectic soldering processes.
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.

Layout recommendation
The radiated EMI performance of the DC/DC regulator will
depend on the PCB layout and ground layer design.
It is also important to consider the stand-off of the DC/DC
regulator.
If a ground layer is used, it should be connected to the output
of the DC/DC regulator 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.
See Design Note 022 for detailed information.

Operating information
Extended information for POLA products is found in
Application Note AN206.
Input Voltage
The input voltage range 2.95 to 3.65 Vdc makes the product
easy to use in intermediate bus applications when powered
by a regulated bus converter.
Turn-off Input Voltage
The DC/DC regulators 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 0.05V.
Remote Control {Inhibit}
The products are fitted with a
remote control (Inhibit) function
referenced to the primary negative
input connection (- In), positive
logic. The INHIBIT function allows
the regulator to be turned on/off by
an external device like a
semiconductor or mechanical
switch.
The regulator will turn on when the input voltage is applied
with the INH pin open. Turn off is achieved by connecting the
INH pin to the - In. To ensure safe turn off the voltage
difference between INH pin and the - In pin shall be less than
0.6V. The regulator will restart automatically when this
connection is opened.

External Ca

acitors
Input capacitors:
The recommended input capacitors are determined by the
470 µF minimum capacitance and 800 mArms minimum
ripple current rating.
Output capacitors (required):
A 470 µF low-ESR electrolytic output capacitance Is required
to meet specification as defined in the electrical specification.
Output capacitors (optional):
The recommended output capacitance of 200 µF ceramic
capacitor will allow the module to meet its transient response
specification as defined in the electrical specification.
When using one or more non-ceramic capacitors, the
calculated equivalent ESR should be no lower than 4 m
(Use
7 m as the minimum when using max-ESR values to
calculate).
Input And Output Impedance
The impedance of both the input source and the load will
interact with the impedance of the DC/DC regulator. It is
important that the input source has low characteristic
impedance. The regulators 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 regulator will ensure stable operation.
The capacitor is not required when powering the DC/DC
regulator 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 by addition of decouplin
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 regulator 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 m across the output connections.
For further information please contact your local Ericsson
Power Modules representative.
Remote Sense
The DC/DC re
g
ulators 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 0.3v voltage drop
between output pins and the point of load.
If the remote sense is not needed, Vsen can be left open.
Over Current Protection (OCP)
The regulators include current limiting circuitry for protection
at continuous overload.
The output voltage will decrease towards zero for output
currents in excess of current limit threshold. The re
g
ulator will
resume normal operation after removal of the overload. The
load distribution should be designed for the maximum output
short circuit current specified. The current limit operation is a
“hick up” mode.
Generation of the BusTermination Voltage
The voltage at VREF is the reference volta
g
e for the s
y
stem bus
receiver comparators. It is normally set to precisely half the
bus driver supply voltage (VDDQ/2), using a resistor divider.
The Thevenin impedance of the network driving the VREF pin
should not exceed 500 ohm
The module senses VREF to regulate the output voltage VTT, the
required bus termination supply voltage. VTT is active about
20 ms after a valid VREF input source is applied to the module.
Once active VTT will track the voltage applied at VREF.

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
TBD
Thermal Consideration
General
The regulators 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 regulator. Increased airflow enhances the
cooling of the regulator.
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 = 3.3 V.
The DC/DC regulator is tested on a 254 x 254 mm,
35 µm (1 oz), 8-layer test board mounted vertically in a wind

Soldering Information - Surface mounting
The surface mount version of the product is intended for
convection or vapor phase reflow Pb-free processes. To
achieve a good and reliable soldering result, make sure to
follow the recommendations from the solder paste supplier,
to use state-of-the-art reflow equipment and reflow profiling
techniques as well as the following guidelines.
A no-clean flux is recommended to avoid entrapment of
cleaning fluids in cavities inside of the DC/DC regulator. The
cleaning residues may affect long time reliability and isolation
voltage.
Minimum pin temperature recommendations
Pin number 9 is chosen as reference location for the minimum
pin temperature recommendations since this will be the
coolest solder joint during the reflow process.
SnPb solder processes
For Pb solder processes, a pin temperature (TPIN) in excess of
the solder melting temperature, (TL, +183 °C for Sn63/Pb37)
for more than 30 seconds, and a peak temperature of
+210 °C is recommended to ensure a reliable solder joint.
Lead-free (Pb-free) solder processes
For Pb-free solder processes, a pin temperature (TPIN) in
excess of the solder melting temperature (TL, +217 to +221 °C
for Sn/Ag/Cu solder alloys) for more than 30 seconds, and a
peak temperature of +235 °C on all solder joints is
recommended to ensure a reliable solder joint.
Maximum regulator temperature requirements
To avoid dama
g
e or performance de
g
radation of the product,
the reflow profile should be optimized to avoid excessive
heating. The maximum product temperature shall be
monitored by attaching a thermocoupler to the top of the
main transformer.
A sufficiently extended preheat time is recommended to
ensure an even temperature across the host PCB, for both
small and large devices. To reduce the risk of excessive
heating is also recommended to reduce the time in the reflow
zone as much as possible.
SnPb solder processes
For conventional SnPb solder processes, the product is
qualified for MSL 1 according to IPC/JEDEC standard
J-STD-020C.
During reflow, TP must not exceed +225 °C at any time.
Lead-free (Pb-free) solder processes
For Pb-free solder processes, the product is qualified for
MSL 3 according to IPC/JEDEC standard J-STD-020C.
During reflow, TP must not exceed +260 °C at any time.

Soldering Information — Through Hole Mounting
The through hole mount version of 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 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.
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.
