PKG 4000 I
30–60 W DC/DC Power Modules
48 V Input Series
The PKG series of DC/DC Power Modules are mem-
bers of the EriPower™ range of low profile DC/DC
converters for distributed power architectures in
48/60 VDC power systems. They provide up to 60W
in single and dual output versions. Utilizing the
standard EriPower™ PKA/PKE pin-out with an even
smaller footprint, the power density is 20 W/cu.in.
The PKG units can be used as on-board distributed
power modules, or serve as building blocks for more
centralized power boards. The high efficiency makes it
possible to operate over a wide temperature range
without any extra heatsinks. At forced convection
cooling >200 lfm (1 m/s), the PKG units can deliver
full power without heatsinks up to +65°C ambient.
With derated output power it can also operate in
temperature controlled environments with non-forced
convection cooling. By adding external heatsinking,
the temperature range can be extended even further.
Thanks to its peak power capa-bility, the PKG series
is ideal for applications where max power is only
required during short durations e.g. in disc drives.
The PKG series uses ceramic sub-strates with plated
copper in order to achieve good thermal manage-
ment, 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

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.

Safety
The PKG 4000 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 isolation is an opera-
tional insulation in accordance with EN
60 950.
The PKG DC/DC power modules are re-
cognized 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 is intended to
be supplied by isolated secondary circuitry
and shall be installed 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 provided 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 con-
nection 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 isolation voltage is a galvanic isolation
and is verified in an electric strength test.
Test voltage 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 decreased 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 @ 50 Vdc.
Flammability ratings of the terminal support
and internal plastic construction details
meets UL 94V-0.
Note:
1)The input voltage range 38...72 V meets the
requirements in the European Telecom Standard
prETS 300 132-2 for Normal input voltage
range in 48 V and 60 V DC power systems,
–40.5...–57.0 V and –50.0...–72.0 V
respectively. At input voltages exceeding 72 V
(abnormal voltage) the power loss will be higher
than at normal input voltage and TC must be
limited to max +90 °C. Absolute max con-
tinuous input voltage is 80 V dc. Output
characteristics will be marginally affected at
input voltages exceeding 72 V.
