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 two

different methods, Ericsson failure rate data system

DependTool and Telcordia SR332.

Predicted MTBF for the series is:

- 3.15 million hours according to DependTool.

- 1.67 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 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.

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

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.

Output Ripple & Noise Output Load Transient Response

Output voltage ripple (20mV/div.) at:

Tref = +25°C, IO = 40 A resistive load,

VI = {53 V}. Time scale: 2 μs/div.

See the filter in the Output ripple and noise

section (EMC Specification).

Output voltage response to load current step-

change (10-30-10 A) at:

Tref =+25°C, VI = 53 V.

Top trace: output voltage (100mV/div.).

Bottom trace: load current (20 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((2.5(100+Δ%))/1.225Δ%-(100+2Δ%)/Δ%) kOhm

Eg Increase 4% =>Vout =2.6 Vdc

5.11(2.5(100+4)/1.225x4-(100+2x4)/4 = 133 kOhm

Output Voltage Adjust Downwards, Decrease:

Radj= 5.11(100/Δ%-2) kOhm

Eg Decrease 2% =>Vout = 2.45 Vdc

5.11(100/2-2)= 245 kOhm

The PKM4000D series DC/DC converters can be

offered with a baseplate. Baseplate helps to cool

hotspots more efficient during heavy load. The

baseplate have approximately 5°C improved

derating compared to datasheet showing non

baseplated PKM4000D. The baseplate is

intended to be mounted on a cold wall to transfer

heat away from the converter. By mounting

PKM4000D in this way thermal derating can be

improved by more than 10°C .

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((3.3(100+Δ%))/1.225Δ%-(100+2Δ%)/Δ%) kOhm

Eg Increase 4% =>Vout =3.43 Vdc

5.11(3.3(100+4)/1.225x4-(100+2x4)/4 = 220 kOhm

Output Voltage Adjust Downwards, Decrease:

Radj= 5.11(100/Δ%-2) kOhm

Eg Decrease 2% =>Vout = 3.23 Vdc

5.11(100/2-2)= 245 kOhm

The PKM4000D series DC/DC converters can be

offered with a baseplate. Baseplate helps to cool

hotspots more efficient during heavy load. The

baseplate have approximately 5°C improved

derating compared to datasheet showing non

baseplated PKM4000D. The baseplate is intended

to be mounted on a cold wall to transfer heat away

from the converter. By mounting PKM4000D in

this way thermal derating can be improved by

more than 10°C .

The PKM4000D series DC/DC converters can be offered with a

baseplate. Baseplate helps to cool hotspots more efficient during

heavy load. The baseplate have approximately 5°C improved

derating compared to datasheet showing non baseplated PKM4000D.

The baseplate is intended to be mounted on a cold wall to transfer

heat away from the converter. By mounting PKM4000D in this way

thermal derating can be improved by more than 10°C .

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.

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

and improve the high frequency EMC performance.

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 Tref must be limited to absolute max

+110°C. The absolute maximum continuous input voltage is

80Vdc.

Turn-off Input Voltage

The PKM 4000DSeries 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.

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

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 4000DSeries DC/DC converters

have been desi

ned to be completel

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

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 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.

For further information please contact your local Ericsson

Power Modules representative.

Output Voltage Adjust (Vadj)

All PKM 4000DSeries 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.

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.

Operating information continued

Parallel Operation

The PKM 4000DSeries 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

4000D Series DC/DC converters for increased power without

using external current sharing circuits.

See Design Note 006 for detailed information.

Remote Sense

All PKM 4000DSeries 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

e and the volta

e at the output pins. The output volta

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 4000DSeries 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 (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 4000DSeries 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)

The PKM 4000DSeries 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 PKM 4000DSeries 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 accordin

to the information

iven 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

by measuring 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.

See Design Note 019 for further information.

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

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 4110D PINB 53v full load at 2m/s:

1. (( ) - 1) × 115 W = 14.2 W

2. 14.2 W × 4°C/W = 56°C

3. 110 °C - 56°C = max ambient temperature is 54°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
