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:
- 3.87 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 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, signalling, transmission as well as network
management for telecommunication
(Note: the products are manufactured in lead-free
soldering processes and the lead present 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.

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.

Operating information
Extended information for POLA products is found in
Application Note POLA.
Input Voltage
The input voltage range 10.8 to 13.2 Vdc makes the product
easy to use in intermediate bus applica tions whe n powe red
by a regulated bus converter.
Turn-off Input Voltage
The DC/DC regulators monitor the input vol tage and will turn
on and turn off at predetermined levels.
The minimum hysteresis between turn on and turn off input
voltage is 50mV.
Remote Control (RC) Inhibit
The products are fitted with a
remote control 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 INHIBIT pin has an
internal pull up resistor to + In.
The regulator will turn on when the input vo ltage is applied
with the INHIBIT pin open. Turn off is achieved by connecting
the INHIBIT pin to the - In. To ensure safe turn off, the volta
g
e
difference between INHIBIT pin and the - In pin shall be less
than 0.6V. The regulator will restart automa tically when this
connection is opened.

External Ca
p
acitors
Input capacitors:
The recommended input capacitors are determined by the
560 µF minimum capac itance and 800 mArms minimum
ripple current rating.
Output capacitors (optional):
The recommended output capac itance of 330 µF 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 mΩ
(7mΩ using the manufacturer’s maximum ESR for a single
capacitor).
Input And Output Impedance
The impedance of both the input source a nd 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 inductanc e , the a ddition o f a 100 µF capacitor
across the input of the regulator will e nsure 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 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 ca pac itors to lowe r the effective ESR.
The ceramic capacitors will handle high-frequency dynamic
load changes while the electrolytic capacitors are used to
handle low frequency dyna mic 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 be come 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 mΩ across the output connections.
For further information please contact your local Ericsson
Power Modules representative.
Output Voltage Adjust (V
adj
)
The DC/DC regulators have an Output Voltage Adjust pin
(V
adj
). This pin can be used to adjust the output voltage above
or below Output voltage initial setting.
To increase or decrease the voltage the resistor should be
connected between the V
adj
pin and GND pin. The resistor
value of the Output voltage adjust function is according to
information given under the Output section for the respective
product.
Parallel Operation
Two regulators may be paralle le d for redundancy if the total
power is equal or less than P
O
max. It is not recommended to
parallel the regulators without using external current sharing
circuits.
Remote Sense
The DC/DC regulators 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 re mote
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 +Sense should be left
open.
Over Temperature Protection (OTP)
The PMH and PMJ family regulators are protected from
thermal overload by an internal over temperature shutdown
circuit.
When the internal temperature exceeds the OTP threshold,
the regulator will shut down. The DC/DC re gulator will make
continuous attempts to start up (soft-start mode) and resume
normal operation automatically when the temperature has
dropped >10°C below the temperature threshold.
Over Current Protection (OCP)
The regulators include current limiting circuitry for protection
at continuous overload.
The output voltage will dec rease towards zero for output
currents in excess of the over-current threshold. The regulator

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 current limit.
Soft-start Power Up
From the moment a valid input voltage is a pplied, the soft-
start control introduces a short time-delay (typically 5-10 ms)
before allowing the output voltage to rise.
The initial rise in input current when the input voltage first
starts to rise is the charge current drawn by the input
capacitors. Power-up is complete within 15 ms.
Auto-Track™ Fu n cti on
Auto-Track was designed to simplify the amount of circuitry
required to make the output vltage from each module power
up and power down in sequence. The sequencing of two or
more supply voltages during power up is a common
requirement for complex mixed-signal applications, that use
dual-voltage VLSI ICs such as DSPs, micro-processors and
ASICs.
Margin Up/Down controls
These controls allow the input voltage to be momentarily
adjusted, either up or down, by a nominal 5 %. This provides
a convenient method for dynamically testing the operation of
the load circuit over its supply margin or range. It can also be
used to verify the function of supply voltage supervisors.
Pre-Bias Startup Ca pability
This often occurs in complex digital systems when current
from another power source is backfed through a dual-supply
logic component, such as FPGA or ASIC.
The PMH(3.3/5.0V Vin) incorporate synchronous rectifiers, but
will not sink current durin
g
startup, or whenever the Inhibit pin
is held low. However, to ensure satisfactory operation of this
function, certain conditions must be maintained.
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 gra p h found in the Output
section for each model provides the available output current
vs. ambient air temperature and air velocity at V
in
= 12 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
tunnel with a cross-section of 305 x 305 mm.
Proper cooling of the DC/DC regulator can be verified by
measuring the temperature at positions P1, P2 and P3. 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 T

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

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.
