The PKJ series represents a “third generation” of High

The PKJ series also offers the flexibility of using a heatsink

Density DC/DC Power Modules providing 90% efficiency.

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.

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 batter-

ies 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 Components AB has been

an ISO 9001 certified supplier since 1991. For product
