PKG2610PI - Ericsson Components

46–60 W DC/DC Power Modules

24 V Input Series

• Efficiency typ 84% at 5 V and full

load

• Low profile 11.0 mm (0.43 in.)

• 1,500 V dc isolation voltage

(duals = 1,000 Vdc )

• MTBF >200 years at +75°C case

temperature

• Rugged mechanical design and

efficient thermal management, max

+100°C case temperature

• EMI measured according to

EN 55 022 and FCC part 15J

The PKG 2000 I series of low profile DC/DC Power

Modules are intended as distributed power sources in

decentralized +24 V DC power systems. They can be

used as on-board distributed power modules, or serve

as building blocks for more centralized power boards.

The PKG series of DC/DC power modules provide up

to 60W of output power utilizing the standard

EriPower™ PKA/PKE pin-out, with an even smaller

footprint, and a power density of 20 W/cu.in.

The high efficiency makes it possible to operate over

a wide temperature range without any extra heat-

sinks. At forced convection cooling >200 lfm (1 m/s),

the PKG units can deliver full power without

heatsinks up to +60°C ambient. With derated output

power it can also operate in temperature controlled

environments with free convection cooling. By adding

external heatsinking, the temperature range can be

extended even further. Thanks to their peak power

capability, the PKG series is ideal for applications

where max power is only required during short

durations e.g. in disc drives.

The PKG series use ceramic substrates with plated

copper in order to achieve good thermal management,

low voltage drops and a high efficiency.

These products are manufactured using highly

automated manufacturing lines with a world-class

quality commitment and a five-year warranty. Ericsson

Microelectronics AB has been an ISO 9001 certified

supplier since 1991. For a complete product program please

General

Safety

The PKG 2000 I Series DC/DC power mod-

ules are designed in accordance with EN 60

950, Safety of information technology equipment

including electrical business equipment and certi-

fied by SEMKO.

The PKG power modules are recognized by

UL and meet the applicable requirements in

UL 1950 Safety of information technology equip-

ment, the applicable Canadian safety require-

ments and UL 1012 Standard for power sup-

plies.

The DC/DC power module shall be installed

in an end-use equipment and considerations

should be given to measuring the case tem-

perature to comply with TCmax when in

operation. They are intended to be supplied

by isolated secondary circuitry and shall be

installed in compliance with the require-

ments of the ultimate application. If connect-

ed to a 24 V DC power system reinforced

insulation must be provided in the power

supply that isolates the input from the ac

mains. The isolation in the DC/DC power

module is an operational insulation in accord-

ance with EN 60 950. One pole of the input

and one pole of the output is to be grounded

or both are to be kept floating.

The terminal pins are only intended for

connection to mating connectors of internal

wiring inside the end-use equipment.

The isolation voltage is a galvanic isolation

and is verified in an electric strength test.

Test voltage (VISO) between input and output

and between case and output is

1,500 Vdc (duals = 1,000 V dc) for 60 s.

In production the test duration may be de-

creased to 1 s.

The capacitor between input and output has a

value of 4.7 nF (duals = 22 nF) and the leak-

age current is less than 1mA @ 26 Vdc.

Flammability ratings of the terminal support

and internal plastic construction details

meets UL 94V-0.

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. If exposed to stress above these limits, function and performance may degrade in an unspecified

manner.

Thermal Data

Two-parameter model

Power dissipation is generated in the components mounted on the

ceramic substrate. The thermal properties of the PKG DC/DC power

module is determined by thermal conduction in the connected pins

and thermal convection from the substrate via the case.

The two-parameter model characterize the thermal properties of the

PKG power module and the equation below can be used for thermal

design purposes if detailed information is needed. The values are given

for a power module mounted on a printed board assembly (PBA).

Note that the thermal resistance between the substrate and the air,

Rth sub-A is strongly dependent on the air velocity.

Tsub = Pd × Rth sub-P × Rth sub-A/(Rth sub-P + Rth sub-A) + (TP–TA)

× Rth sub-A/(Rth sub-P + Rth sub-A) + TA

Where:

Pd: dissipated power, calculated as PO × (1/h-1)

Tsub : max average substrate temperature, » TC

max

TA: ambient air temperature at the lower side of the power

module

TP: average pin temperature at the PB solder joint

Rth sub-P : thermal resistance from Tsub to the pins

Rth sub-A : thermal resistance from Tsub to TA

v : velocity of ambient air.

Air velocity in free convection is 0.2– 0.3 m/s (40-60 lfm).

Over Temperature Protection (OTP)

The PKG DC/DC power modules have an internal over temperature

protection circuit. If the case temperature exceeds min +115 °C the

power module will go in to OTP-mode. As long as the case tempera-

ture exceeds min +115 °C the power module will operate in OTP-

mode.

During OTP-mode the output voltage pulsates between zero and

nominal output voltage, which reduces the power loss inside the

power module. The PKG DC/DC power module will automatically

resume normal operation when the temperature decreases below

min +115 °C.

Operating information

Current Limiting Protection

The output power is limited at loads above the output current limit-

ing threshold (Ilim), specified as a minimum value.

Turn-on/off Input Voltage (TOA)

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

turn off at predetermined levels. The levels can be decreased by means

of an external resistor connected between pin 2 and pin 4.

A 0.2 MW resistor will decrease the turn-off input voltage approxi-

mately 10%.

Input and Output Impedance

Both the source impedance of the power feeding and the load imped-

ance will interact with the impedance of the DC/DC power module.

It is most important to have the ratio between L and C as low as possi-

ble, i.e. a low characteristic impedance, both at the input and output,

as the power modules have a low energy storage capability.

Use an electrolytic capacitor across the input or output if the source or

load inductance is larger than 10 mH. Their equivalent series resistance

together with the capacitance acts as a lossless damping filter. Suitable

capacitor values are in the range 10–100 mF.

Parallel Operation

The load regulation characteristic and temperature coefficient of the

PKG DC/DC Power Modules are designed to allow parallel operation.

Paralleling of several modules is easily accomplished by connection of

the output voltage terminal pins. The connections should be symmet-

rical, i.e. the resistance between the output terminal and the common

connection point of each module should be equal. Good paralleling

performance is achieved if you allow the resistance to be 10 mW.

10 mW equals 50 mm (2 in) of 35 mm (1 oz/ft2) copper with a trace

width of 2.5 mm (0.1 in).

It is recommended not to exceed PO =n × 0.8 × POmax, where POmax

is the maximum power module output power and n the number of

paralleled units, not to overload any of them and thereby decrease the

reliability performance.

Paralleling performance may be further improved by voltage match-

ing. Voltage matching is accomplished by using the Output Adjust

function and trim the outputs to the same voltage.

Output Voltage Adjust (Vadj)

The utput voltage, VO, can be adjusted by using an external resistor. A

0.1 MW resistor will change VO approximately 5%. To decrease the

output voltage the resistor should be connected between pin 10 and

pin 9 (+Out 1). To increase the output voltage the resistor should be

connected between pin 10 and pin 8 (– Out 1).

Maximum Capacitive Load

The PKG series has no limitation of maximum connected capacitance

on the output. The power module may operate in current limiting

mode during start-up, affecting the ramp-up and the start-up time.

For optimum performance we recommend maximum 100 mF/A of IO

for dual outputs. Connect capacitors at the point of load for best per-

formance.

Remote Control (RC)

Remote turn-on and turn-off can be realized by using the RC-pin.

Normal operation is achieved if pin 1 is open (NC). If pin 1 is con-

nected to pin 3 the PKG power module turns off. To ensure safe turn-

off the voltage difference between pin 1 and 3 shall be less than 1.0 V.

RC is TTL open collector compatible (see fig. 1).

Over Voltage Protection (OVP)

The PKG series has an internal Over Voltage Protection circuitry. The

circuitry will detect over voltage conditions on the output and stop

the power module operation. During OVP conditions there are contin-

uous attempts to start up (non-latching mode). If latching mode is

preferred an external circuit can be used to change the function and

make the output remain in off mode after over voltage detection. (The

OVP level can be found in the output data section.)

Quality Statement

The products are designed and manufactured in an industrial environ-

ment where quality systems and methods like ISO 9000, 6s and SPC,

are intensively in use to boost the continuous improvements strategy.

Infant mortality or early failures in the products are screened out by a

burn-in procedure and 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.

Reliability

Meantime between failure (MTBF) is calculated to >1.7 million hours

at full output power and a case temperature of +75°C (TA =+40 °C),

using the Ericsson failure rate data system. The Ericsson failure rate

data system is based on field failure rates and is continously updated.

The data correspond to actual failure rates of component used in Infor-

mation Technology and Telecom equipment in temperature controlled

environments (TA =–5…+65°C). The data is considered to have a

confidence level of 90%. For more information see Design Note 002.
