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.
