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. If exposed to
stress above these limits, function and
performance may degrade in an unspeci-
fied manner.

Thermal Data
Reflow Soldering Information
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. Neglec-
ting the soldering information given below may result in perma-
nent damage or significant degradation of power module per-
formance.
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
ex-tended time to reach peak temperatures, would then be
suitable.
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:
T
PB = (TC–TA)×(Rth C–PB+Rth C–A)/Rth C–A–Pd×Rth C–PB+TA
Where:
Pd:
TC:
dissipated power, calculated as PO ×(l/h–1)
max average case temperature
TA:
ambient air temperature at the lower side of the power
module
TPB
:
temperature in the PB between the PKF connection pins
Note! These are maximum parameters. Depending on process
variations, an appropriate margin must be added.
Rth C-PB: thermal resistance from case to PB under the power
module
R
v:
R
th C-A: thermal resistance from case to ambient air
velocity of ambient air.
th 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 tem-perature
(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
The PKF 2000 I series DC/DC power modules are designed in
accordance with EN 60 950, Safety of information technology
equipment including electrical business equipment. SEMKO certificate
no. 9738248.
The PKF power modules are recognized by UL and meet the
applicable requirements in UL 1950 Safety of information technology
equipment, the applicable Canadian safety requirements and UL
1012 Standard for power supplies.
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 TCmax 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.
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. 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.
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 Vdc 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 @ 26 Vdc.
The case is designed in non-conductive epoxy. Its flamma-bility
rating meets UL 94V-0. The oxygen index is 34%.

To increase VIon a resistor should be connected between pin 11
and 18 (see fig. 3).
Operating Information
Fuse Considerations
The resistance is given by the following equation
(For VIon>18.4V):
To prevent excessive current from flowing through the input
supply line, in the case of a short-circuit across the converter in-
put, 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:
R
Ion = (k1 – VIon)/(VIon – k2) kW
where k2 is the typical unadjusted turn-on input voltage (V).
To decrease VIon a resistor should be connected between pin 10
and 11 (see fig. 3). The resistance is given by the following
equation (for 17.0V < VIon >18.3V:

Remote Control (RC)
Turn-off level. VIoff is the adjusted turn-off level and is deter-
mined by the following equation: VIoff = VIon – 1.5V (typical
value).
Turn-on or turn-off can be realized by using the RC-pin. Normal
operation is achieved if pin 11 is open (NC). If pin 11 is con-
nected to pin 18 the power module turns off. To ensure safe turn-
off the voltage difference between pin 11 and 18 shall be less than
1.0V. RC is an TTL open collector compatible output with a sink
capacity >300 mA (see fig. 1).

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 is not connected to-
gether the output will decrease to a low value. To increase VO a
resistor should be connected between pin 8/9 and 18, and to
decrease VO a resistor should be connected between pin 8 and 9
(see fig. 4).

Over Voltage Protection (OVP)
The remote control can be utilized also for OVP by using the ex-
ternal circuitry in figure 2. Resistor values are for 5V output app-
lications, but can easily be adjusted for other output voltages and
the desired OVP level.

Turn-on/off Input Voltage
The power module monitors the input voltage and will turn on
and off at predetermined levels. The typical turn-on level (with-
out any external resistor) is 18.4 V and the typical turn-off level is
17.0 V, a slight deviation can occur due to tolerances in the
manufacturing process. These levels can be adjusted by means of
external resistors.

Capacitive Load
Delivery Package Information
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 perfor-
mance.
Tubes
The PKF-series is delivered in tubes (designated by /A) with a
length of 500 mm (19.69 in), see fig. 5.
Parallel Operation
Paralleling of several converters is easily accomplished by direct
connection of the output voltage terminal pins. The load regula-
tion 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.

Input and Output Impedance
Both the source impedance of the power feeding and the load im-
pedance 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
inductance is larger than 10 mH. Their equivalent series resist-
ance together with the capacitance acts as a lossless damping fil-
ter. Suitable capacitor values are in the range 10–100 mF.
