The PKJ series represents a “third generation” of High
Density DC/DC Power Modules providing high efficiencies.
To achieve this high efficiency, Ericsson uses proprietary drive
and control circuits with planar magnetics and low resistivity
multilayer PCB technology, and a patent pending topology
with active rectification. The PKJ series can be used without
bulky and height consuming heatsinks, resulting in a lower
total cost. This also provides narrow board spacing for elec-
tronic, shelf based applications.
The PKJ series also offers the flexibility of using a heatsink
when needed, enabling reduced airflow, extended reliability
or higher ambient temperature operation in a wide range of
48V and 60V DC powered systems. Similar to other
Ericsson Power Modules, the PKJ series includes an under-
voltage shut down facility, protecting the associated batteries
from being too deeply discharged. The PKJ series also offers
over-voltage protection, over-temperature protection and is
short circuit proof.
The products are in the industry standard package size and
offer a beneficial alternative to competing products on the
market. Because for certain applications they may not
require heatsinks, they are ideal for cost sensitive or high-
density applications.
These products are manufactured using highly automated
manufacturing lines with a world-class quality commitment
and a five-year warranty. Ericsson Microelectronics has been
an ISO 9001 certified supplier since 1991.

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.
