required
The PKD 4000 SI series of DC/DC power modules
are intended to be used as distributed power sources
in decentralized 48/60VDC power systems. The PKD
series use a ceramic substrate with thickfilm tech-
nology and a high degree of silicon integration. That,
together with the electrical design using synchronous
rectification gives good thermal management, high
reliability and high efficiency.
can deliver full power up to +70°C ambient tempera-
ture. The high reliability and the low profile of the
PKD series makes them particularly suited for Infor-
mation Technology and Telecom (IT&T) applications
with board spacing down to 15mm (0.6 in.).
These products are manufactured using highly auto-
mated manufacturing lines with a world-class quality
commitment and a five-year warranty.
The high efficiency makes it possible to operate over a
wide temperature range without a heatsink. At forced
convection cooling >200lfm (1m/s), the PKD units
Ericsson Microelectronics AB has been an ISO 9001
certified supplier since 1991. For product program please
reference the back cover.

General
The PKD 4000 SI Series DC/DC power
modules are designed in accordance with
EN 60 950 Safety of information technology
equipment including electrical business
equipment, and certified by UL.

The PKD DC/DC power modules are re-
cognized by UL and meet the applicable re-
quirements in UL 1950 Safety of information
technology equipment, the applicable Cana-
dian safety requirements and UL 1012 Stan-
dard for power supplies. The DC/DC power
module shall be installed in an end-use
equipment and is intended to be supplied by
isolated secondary circuitry and shall be in-
stalled in compliance with the requirements
of the ultimate application. 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 60 V DC power
system reinforced insulation must be pro-
vided in the power supply that isolates the
input from the ac 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. The terminal
pins are only intended for connection to
mating connectors of internal wiring inside
the end-use equipment.

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 (VOac)
Output ripple is measured as the peak to peak voltage of the
fundamental switching frequency
The capacitors are ceramic type. Low ESR is critical for
achieveing these results.
Operating information
Maximum capacitive load
The PKD series of converters has no limitation of maximum
connected capacitance on the output. Capacitance on the
output will affect the ramp-up and the start-up time.
Parallel operation
For safe parallel operation a low voltage drop diode must be
connected in series with each output.
Series operation
If sense pins are directly connected to output on each mo-
dule it is possible to connect modules in series.

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 mo-
dules have a low energy storage capability. Use an electro-
lytic capacitor across the input if the source inductance is
larger than 10 µH.
The equivalent series resistance of these capacitors
together with the capacitance acts as a lossless damping
filter. Suitable capacitor values are in the range 10 –100 µF.
Tested in windtunnel with a cross section of 305×305mm mounted
on a 2 layer PCB with a size of 230×160mm.
Airspeed measured at module.
Calculation of temperature increase of case
1. First we need to know the powerloss by using the for-
mula:
1
(( ) - 1) × output power = losses.
η
Protection and control function
η = efficiency of converter. E.g 89% = 0.89
Remote Control pin (RC)
The PKD power modules are offered with either positive or
negative logic to turn the converter on or off.
2. Then we take the powerlosses × thermal resistance at
the air speed in your system. This gives the temperature
increase.
The SI version has positive logic and the converter will turn
on if the input voltage is applied with the RC pin open. Turn
off is achieved by connecting the RC pin to the minus input.
To ensure safe turn off of the SI version the voltage differ-
ence between negative input pin (–In) and the remote control
pin (RC) shall be less than 0.6V. The converter will restart
when this connection is opened.
The SIN version has negative logic and will be off until the
RC pin is connected to the minus input.
To turn on the SIN version the voltage between RC pin and
minus input should be less than 1V.
3. Max allowed ambient temperature, is max allowed case
temperature (100°C) – temperature increase.
E.g PKD 4210 at 1m/s:
1
A. ((
) - 1) × 26.5W = 3.275W
0.89
B. 3.275W × 9.0°C/W = 29.5°C
C.100°C - 29.5°C = max ambient temperature is 70.5°C
To turn off the SIN version the RC pin should be left open, or
should be connected to a voltage higher than 4V referenced
to minus input. RC is CMOS open drain compatible. Current
is less than 1mA and voltage less than 15V.
The real temperature will be dependent on several factors
like PCB size, direction of air flow, air turbulence etc. Please
always verify by testing.
Soldering information
The PKD series of DC/DC power modules are manufac-
tured in surface mount technology. Extra precautions must
therefore be taken when reflow soldering. Neglecting the
soldering information given below may result in permanent
damage or significant degradation of power module perfor-
mance.
The PKD series can be reflow soldered using Natural Con-
vection, Forced Convection Technologies. The high thermal
mass of the component and its effect on temperature re-
quires that particular attention be paid to other temperature
sensitive components.
Please measure temperatures on pin: 22
Ramp and slope: max 4°C per second.
1) Solder with a melting point approximately 180°C.
2) Solder with a melting point approximately 220°C.

Output voltage adjust (Vadj)1)
Delivery Package Information
Output voltage, VO, can be adjusted by using an external re-
sistor. To decrease the output voltage the resistor should be
connected between pin 16 and pin 15 (+Sense). To increase
the output voltage the resistor should be connected between
pin 16 and pin 17 (-Sense).
Trays

Sense leads1)
All PKD 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 a current less than 50mA, 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.

50 pcs (one box contains
5 full trays)
The power module will compensate for up to 10% voltage
drop between the sensor voltage and the voltage at the
power module output pins. 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 PKD DC/DC power modules are protected from thermal
over load by an internal over-temperature shutdown circuit.
When the case temperature exceeds +130°C 15°C the
converter will automatically shut down. The converter will
automatically restart when temperature is below +115°C.
Layout recommendation
The radiated EMI performance of the power module will be
optimized by including a ground plane in the PCB area under
the module. This approach will return switching noise to
ground as directly as possible, with improvements to both
emissions and susceptibility. If one ground trace is used, it
should be connected to the input return. Alternatively, two
ground traces may be used, with the trace under the input
side of the module connected to input return and the trace
under the output side of the module connected to the output
return. Make sure to use appropriate safety isolation spac-
ing between these two return traces. The use of two traces
as described will provide the capability of routing the input
noise and output noise back to their respective returns.
1) When using the output voltage adjust or the sense pins to increase
the output voltage, full positive adjust range, can only be guaranteed
above 40V input voltage.
