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
program please reference the back cover.
