The PKL series represents another one of Ericsson’s “industry
first” achievements in the continued development of our “Third
Generation” of high-density, high-efficiency power modules.
This module packs 51.7 W/in
3
at 87% efficiencies (2.5V @
60A) in an industry standard footprint that has been enhanced to
include two additional output pins for motherboard connection
reliability. These breakthrough features come from using the most
advanced patented topology utilizing integrated magnetics and
synchronous rectification on a low-resistivity multilayer PCB.
This product features fast dynamic response times and low
output ripple, which are important parameters when supplying
low-voltage logics. The PKL series also is especially suited for
limited board space and high dynamic load applications.
Ericsson’s PKL Power Module has been designed with the
converging “New Telecoms” market in mind, by specifying
the input voltage range in accordance with ETSI specifications.
The PKL series also offers over-voltage protection, under-volt-
age protection, over-temperature protection, soft-start, and is
short circuit proof.
These modules are manufactured on highly automated
manufacturing lines. Ericsson’s world-class quality commitment
is reflected in our standard five-year warranty. Ericsson
Microelectronics has been an ISO 9001 certified supplier
since 1991.

Absolute Maximum Ratings
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.
