The MacroDens™ PKF 5000 I series true component
level on-board DC/DC power modules are intended
as distributed power sources in decentralized 24, 48
and 60 V DC power systems. Utilization of thick film
technology and a high degree of silicon integration
has made it possible to achieve a MTBF of more than
4.9 million hour.
The highly reliable and rugged over-moulded design
and the ultra low height of these DC/DC power
modules makes them particularly suited for Information Technology and Telecom (IT&T) and other
demanding industrial applications, with board
spacing down to 15 mm or 0.6 in. These DC/DC
power modules are optimized for free convection
cooling and have an operational ambient temperature
E
range in compliance with present and future
application needs, including non temperature controlled environments.
The mechanical design offers the choice of surface
mount or through-hole versions, delivered in readyto-use tubes, trays or tape & reel package, and
compatibility with semi and fully aqueous cleaning
processes.
The PKF series is 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

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
Reflow Soldering Information
Over-temperature protection
The PKF series of DC/DC power modules are manufactured in surface
mount technology. Extra precautions must therefore be taken when
reflow soldering the surface mount version. Neglecting the soldering
information given below may result in permanent damage or significant degradation of power module performance.
The PKF series can be reflow soldered using IR, Natural Convection,
Forced Convection or Combined IR/Convection Technologies. The high
thermal mass of the component and its effect on DT (°C) requires that
particular attention be paid to other temperature sensitive components.
IR Reflow technology may require the overall profile time to be extended to approximately 8–10 minutes to ensure an acceptable DT.
Higher activity flux may be more suitable to overcome the increase in
oxidation and to avoid flux burn-up.
The general profile parameters detailed in the diagram, with this extended time to reach peak temperatures, would then be suitable.
Note! These are maximum parameters. Depending on process variations, an appropriate margin must be added.
The PKF 5000 series will automatically shut down when the internal
junction temperature of the control IC in the converter reaches typ.
150 °C.
It will automatically re-start when the junction temperature cools
below typ. 140 °C.
Two-parameter model
This model provides a more precise description of the thermal characteristics to be used for thermal calculations.
Thermally the power module can be considered as a component and
the case temperature can be used to characterize the properties. The
thermal data for a power module with the substrate in contact with
the case can be described with two thermal resistances. One from the
case to ambient air and one from case to PB (Printed Board).
The thermal characteristics can be calculated from the following
formula:
TPB = (TC–TA)×(Rth C–PB+Rth C–A)/Rth C–A–Pd×Rth C–PB+TA
Where:
Pd:
TC:
TA:
dissipated power, calculated as PO ×(l/h–1)
max average case temperature
ambient air temperature at the lower side of the power
module
temperature in the PB between the PKF connection pins
TPB:
Rth C-PB: thermal resistance from case to PB under the power
module
Rth C-A: thermal resistance from case to ambient air
v:
velocity of ambient air.
Rth C-PB is constant and Rth C-A is dependent on the air velocity.
Free convection is equal to an air velocity of approx. 0.2 – 0.3 m/s.
See figure below.
Palladium plating is used on the terminal pins. A pin temperature (Tp)
in excess of the solder fusing temperature (+183°C for Sn/Pb 63/37)
for more than 25 seconds and a peak temperature above 195°C, is
required to guarantee a reliable solder joint.
Both pin 1 and pin 9 must be monitored.
No responsibility is assumed if these recommendations are not
strictly followed.

Safety
Electrical Data
The PKF Series DC/DC power modules are designed in accordance
with EN 60 950, Safety of information technology equipment including
electrical business equipment. SEMKO approval pending.
Fundamental circuit diagrams
Single output
The DC/DC power module shall be installed in an end-use equipment and considerations should be given to measuring the case temperature to comply with TC max when in operation. Abnormal component tests are conducted with the input protected by an external 3 A
fuse. The need for repeating these tests in the end-use appliance shall
be considered if installed in a circuit having higher rated devices.
When the supply to the DC/DC power module meets all the requirements for SELV (<60 V dc), the output is considered to remain within
SELV limits (level 3). The isolation is an operational insulation in
accordance with EN 60 950.
The DC/DC power module is intended to be supplied by isolated
secondary circuitry and shall be installed in compliance with the
requirements of the ultimate application. If they are connected to a
60 V DC 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.
Transient input voltage
The terminal pins are only intended for connection to mating connectors of internal wiring inside the end-use equipment.
These DC/DC power modules may be used in telephone equipment
in accordance with paragraph 34 A.1 of UL 1459 (Standard for Telephone Equipment, second edition).
The galvanic isolation is verified in an electric strength test. Test
voltage (VISO) between input and output is 1,500 V dc for 60 s. In
production the test duration is decreased to 1 s.
The capacitor between input and output has a value of 1 nF and the
leakage current is less than 1µA @ 53 V dc.
The case is designed in non-conductive epoxy. Its flammability
rating meets UL 94V-0. The oxygen index is 34%.
Single voltage pulse at +25 °C ambient temperature.

EMC Specifications
The fundamental switching frequency is 510 kHz ± 26 kHz.
Conducted EMI (input teminals)
EFT
Electrical Fast Transients on the input terminals could affect the
output voltage regulation causing functional errors on the Printed
Board Assembly (PBA). The PKF power modules withstand EFT
levels of 0.5 kV keeping VO within the tolerance band and
2.0 kV without destruction. Tested according to IEC publ. 801-4.
Output Ripple & Noise (VOac)
Output ripple is measured as the peak to peak voltage of the fundamental switching frequency.
Operating Information
Fuse Considerations
PKF series typical conducted EMI performance
Test set up
To prevent excessive current from flowing through the input supply
line, in the case of a short-circuit across the converter input, an
external fuse should be installed in the non-earthed input supply
line. We recommend using a fuse rated at approximately 2 to 4 times
the value calculated in the formula below:
PO max
Iin max =
(hmin × VI min)
For further information, please refer to the fuse manufacturer .
The PKF meets class A in VDE 0871/0878, FCC Part 15J, and CISPR 22
(EN 55022), except for the fundamental switching frequency.
Conducted EMS
Electro Magnetic Susceptibility is measured by injection of electrical disturbances on the input terminals. No deviation outside
the VO tolerance band will occur under the following conditions:
Frequency range
Voltage level
0.15...300 MHz
1.0 Vrms
Remote Control (RC)
Turn-on or turn-off can be realized by using the RC-pin. If pin 11 is
connected to pin 17 the power module turns off. Normal operation is
achieved if pin 11 is open (NC) . To ensure safe turn-off the voltage
difference between pin 11 and 17 shall be less than 2.0 V. RC is an
TTL open collector compatible output with a sink capacity >300 mA
(see fig. 1).
The signal is amplitude modulated with 1 kHz/80% and applied
both differential and common mode.
Radiated EMS (Electro-Magnetic Fields)
Radiated EMS is measured according to test methods in
IEC Standard publ. 801-3. No deviation outside the VO tolerance
band will occur under the following conditions:
Frequency range
0.01...200 MHz
200...1,000 MHz
1...12 GHz

The remote control can also be utilized for OVP by using the external circuitry in figure 2. Resistor values are for 5 V output applications, but can easily be adjusted for other output voltages and the
desired OVP level.

Capacitive Load
Figure 2
The PKF series has no maximum limit for capacitive load 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
start performance we recommend maximum 100 mF/A of IO. Connect
capacitors at the point of load for best performance.
Output Voltage Adjust (Vadj)
Output voltage, VO, can be adjusted by using an external resistor.
Typical adjust range is ± 15%. If pin 8 and 9 are not connected together the output will decrease to a low value.To increase VO a resistor should be connected between pin 8/9 and 17, and to decrease VO a
resistor should be connected between pin 8 and 9 (see fig. 4).
Typical required resistor value to increase VO is given by:
Radj = k1×(k2 – VO)/(VO – VOi), (kW)
where
VO is the desired output voltage
VOi is the typical output voltage initial setting
and

Parallel Operation
Paralleling of several converters is easily accomplished by direct
connection of the output voltage terminal pins. The load regulation
characteristic is specifically designed for optimal paralleling performance. Load sharing between converters will be within ±10%. It
is recommended not to exceed PO = n × 0.9 × PO max, where POmax is
the maximum converter output power and n the number of paralleled
converters, to prevent overloading any of the converters and thereby
decreasing the reliability performance.
Current Limiting Protection (Ilim)
The output power is limited at loads above the output current
limiting threshold (Ilim), specified as a minimum value.
Typical required resistor value to decrease VO is given by:
Radj = k3 × (VOi –VO)/(VO – k4), (kW)
where
k3=13.0
k3=12.6
k3=12.6
k4=2.75

Voltage Margining
For voltage controlled margining e.g. at final test, the following
setup can be used. By increasing the control voltage V1 to +10 V the
output voltage decreases 5% of VOi, and by decreasing V1 to –10 V
the output voltage increases 5%.

Both the source impedance of the power feeding and the load impedance 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
possible, 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 if the source 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.

Quality
Reliability
Meantime between failure (MTBF) is calculated to >4.9 million
hours at full output power and a pin temperature of +55°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 corresponds to actual failure rates of
components used in Information 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.
Quality Statement
The products are designed and manufactured in an industrial environment where quality systems and methods like ISO 9000, 6 s and
