(duals = 1,000 V dc )
• MTBF > 200 years at +75 °C case

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

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 T
C max
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 (V
ISO
) between input and output
and between case and output is
1,500 V dc (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 1
m
A @ 26 Vdc.
Flammability ratings of the terminal support
and internal plastic construction details
meets UL 94V-0.
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.

Note:

The input voltage range 19...36 V meets
the requirements for Normal input voltage
range in 24 V DC power systems, 20…30 V.
At input voltages exceeding 36 V (abnormal
voltage) the power loss will be higher than at
normal input voltage and T
C
must be limited
to max +90 °C. Absolute max continuous
input voltage is 40 V dc. Output characteris-
tics will be marginally affected at 18 V (see
also Turn-off Input Voltage).

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,
R
th sub-A
is strongly dependent on the air velocity.

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.
