The PKM 4000 series represents a “third generation” of High

Density DC/DC Power Modules in an industry standard quarter-

brick package with unparalleled power densities and efficiencies.

These breakthrough performance features have been achieved by

using the most advanced patented topology, utilizing integrated

magnetics and synchronous rectification on a low resistivity

multilayer PCB. The product features fast dynamic response

times and low output ripple, which are important parameters

when supplying low voltage logics. The PKM 4000 series is

especially suited for limited board space and high dynamic load

applications such as demanding microprocessors.

Ericsson’s PKM 4000 Power Modules address the converging

“New Telecoms” market by specifying the input voltage range

in accordance with ETSI specifications. The PKM 4000 series

also offers over-voltage protection, under-voltage protection,

over-temperature protection, soft-start, and is short circuit proof.

These products are manufactured using highly automated

manufacturing lines with a world-class quality commitment

and a five-year warranty. Ericsson Inc., Microelectronics has

been an ISO 9001 certified supplier since 1991.

General

Absolute Maximum Ratings

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.

The isolation is an operational insulation in

accordance with EN 60 950. The DC/DC power

module should be installed in end-use equipment,

in compliance with the requirements of the

ultimate application, and is intended to be

supplied by an isolated secondary circuit.

Consideration should be given to measuring the

case temperature to comply with T_Cmax when in

operation.

When the supply to the DC/DC power

module meets all the requirements for SELV

(<60Vdc), the output is considered to remain

within SELV limits (level 3). If connected to a 60V

DC power system, reinforced insulation must be

provided in the power supply that isolates the

input from the mains. Single fault testing in the

power supply must be performed in combination

with the DC/DC power module to demonstrate

that the output meets the requirement for SELV.

One pole of the input and one pole of the output is

to be grounded or both are to be kept floating.

Safety (continued)

• Isolate the failed module from the input source so that the

remainder of the system may continue operation.

• Protect the distribution wiring from overheating.

The galvanic isolation is verified in an electric strength test. The

test voltage (V_ISO) between input and output is 1,500 Vdc or 60 sec.

Leakage current is less than 1µA @ 50Vdc.

A fast blow fuse should be used with a rating of 10A or less. It is

recommended to use a fuse with the lowest current rating, that is

suitable for the application.

Flammability ratings of the terminal support and internal plastic

construction details meet UL 94V-0.

A fuse should be used at the input of each PKM 4000 series power

module. If a fault occurs in the power module, that imposes a short

on the input source, this fuse will provide the following two functions:

Thermal Design

The thermal data can be used to determine thermal performance

without a heatsink.

For design margin and to enhance system reliability, it is recommended

that the PKM 4000 series DC/DC power modules are operated at case

temperatures below 90°C.

Case temperature is calculated by the following formula:

T_C= T_A+ P_dx R_th^C-A(˚C/W)where P_d= P_O(1/η - 1)

Where:

T_C: Case Temperature

T_A: Local Ambient Temperature

P_d: Dissipated Power

R_th^C-A: Thermal Resistance from T_Cto T_A

P_o: Output Power

η: Efficiency

The efficiency η can be found in the tables on the following pages.

Over Voltage Protection (OVP)

Operating Information

All PKM 4000 DC/DC power modules have latching output

overvoltage protection. In the event of an overvoltage condition, the

power module will shut down. The power module can be restarted

by cycling the input voltage.

Input Voltage

The input voltage range 36...75V meets the requirements in the

European Telecom Standard ETS 300 132-2 for normal input

voltage range in -48V and -60V DC power systems, -40.5...-57.0V

and -50.0...-72.0V respectively. At input voltages exceeding 75V,

the power loss will be higher than at normal input voltage and T_C

must be limited to absolute max +100º C. The absolute max

continuous input voltage is 80V DC.

Turn-(on/off) Input Voltage (V_Ion/V_Ioff)

The power module monitors the input voltage and will turn on and

turn off at predetermined levels. See Input Table on page 2.

Output Voltage Adjust (Trim)

Voltage Trimming

Remote Control (RC)

The PKM 4000 series DC/DC power modules have two remote

on/off options available. Negative logic remote on/off is the standard

option orderable without a suffix added to the part number.

Negative logic remote on/off turns the module off during a logic

high voltage on the on/off pin, and on during a logic low state.

Positive logic remote on/off is orderable by adding the suffix “P” to

the end of the part number. Positive logic remote on/off turns the

module on during a logic high and off during a logic low state.

All PKM 4000 series DC/DC power modules have an Output

Voltage Adjust pin. This pin can be used to adjust the output

voltage above or below V_Oi. When increasing the output voltage,

the voltage at the output pins (including any remote sensing offset)

must be kept below the overvoltage trip point. Also note that at

elevated output voltages the maximum power rating of the module

remains the same, and the output current capability will decrease

correspondingly. These modules trim exactly like the other major

competitors quarter-brick modules.

The RC pin can be wired directly to -In, to allow the module to

power up automatically without the need for control signals.

To decrease V_Oconnect Radj from - SEN to Trim

To increase V_Oconnect Radj from + SEN to Trim

A mechanical switch or an open collector transistor or FET can be

used to drive the RC inputs. The device must be capable of

sinking up to 1mA at a low level voltage of 1.0V, maximum of

15V dc, for the primary RC.

Remote Sense

All PKM 4000 series DC/DC power modules 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 a PCB should be located close to a ground trace

or ground plane. In a discrete wiring situation, the usage of

twisted pair wires or other technique for reducing noise

susceptibility is recommended.

The power module will compensate for up to 0.5V voltage drop

between the sense voltage and the voltage at the power module

output pins. The output voltage and the remote sense voltage

offset must be less than the minimum overvoltage trip point.

Current Limiting

General Characteristics

All PKM 4000 series DC/DC power modules include current

limiting circuitry that makes them able to withstand continuous

overloads or short circuit conditions on the output. The output

voltage will decrease toward zero for heavy overloads.

The power module will resume normal operation after removal of

the overload. The load distribution system should be designed to

carry the maximum short circuit output current specified.

Low resistance and low inductance PCB (printed circuit board) layouts

and cabling should be used. Remember that when using remote

sensing, all the resistance, inductance and capacitance of the

distribution system is within the feedback loop of the power module.

This can have an effect on the modules compensation and the resulting

stability and dynamic response performance.

Paralleling for Redundancy

The figure below shows how n + 1 redundancy can be achieved. The

diodes on the power module outputs allow a failed module to remove

itself from the shared group without pulling down the common output

bus. This configuration can be extended to additional numbers of

power modules and they can also be controlled individually or in

groups by means of signals to the primary RC inputs.

As a rule of thumb, 100 µF/A of output current can be used without

any additional analysis. For example, with a 20A (max P_O100W)

power module, values of decoupling capacitance up to 2000 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 of the remote sensing

loop and close to the load.The absolute maximum value of output

capacitance is 10,000 µF. For values larger than this contact your local

Ericsson representative.

Quality

PKM

Reliability

The calculated MTBF of the PKM 4000 module family is greater than

(>) 2.8 million hours using Bellcore TR-332 methodology. The

calculation is valid for a 90ºC baseplate temperature. Demonstrated

MTBF has been in the range of 3.0 to 3.2 million hours.

Output Ripple & Noise (V_O

)

ac

Output ripple is measured as the peak to peak voltage from 0 to

20MHz which includes the noise voltage and fundamental ripple.

Over Temperature Protection

Quality Statement

The PKM 4000 DC/DC power modules are protected from thermal

overload by an internal over temperature shutdown circuit. When the

case temperature exceeds +110°C (+10, -5°C), the power module will

automatically shut down (latching). To restart the module the input

voltage must be cycled.

The power modules are designed and manufactured in an industrial

environment where quality systems and methods like ISO 9000, 6σ,

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.

Input and Output Impedance

The impedance of both the power source and the load will interact

with the impedence of the DC/DC power module. It is most important

to have the ratio between L and C as low as possible, i.e. a low

characteristic impedance, both at the input and output, as the power

modules have a low energy storage capability. The PKM 4000 series of

DC/DC power modules has been designed to be completely stable

without the need for external capacitors on the input or output when

configured with low inductance input and output circuits. The

performance in some applications can be enhanced by the addition of

external capacitance as described below. If the distribution of the input

voltage source to the power module contains significant inductance,

the addition of a 220-470 µF capacitor across the input of the power

module will help insure stability. This capacitor is not required when

powering the module from a low impedance source with short, low

inductance, input power leads.

Warranty

Ericsson Inc., Microelectronics warrants to the original purchaser or

end user that the products conform to this Data Sheet and are free

from material and workmanship defects for a period of five (5) years

from the date of manufacture, if the product is used within specified

conditions and not opened.

In case the product is discontinued, claims will be accepted up to three

(3) years from the date of the discontinuation. For additional details on

this limited warranty we refer to Ericsson’s “General Terms and

Conditions of Sales,” EKA 950701, or individual contract documents.

Limitation of Liability

Ericsson Inc., Microelectronics 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).

Output Capacitance

When powering loads with significant dynamic current requirements,

the voltage regulation at the load can be improved by the 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 the short duration high frequency components of the

dynamic current requirement. In addition, higher values of electrolytic

capacitors should be used to handle the mid-frequency components. It

is equally important to use good design practices when configuring the

DC distribution system.
