The PKD 4000 SI series of DC/DC power modules
are intended to be used as distributed power sources
in decentralized 48/60VDC power systems. The PKD
series uses a ceramic substrate with thickfilm tech-
nology and a high degree of silicon integration. That,
together with the electrical design using synchronous
rectification gives good thermal management, high
reliability and high efficiency.
The high efficiency makes it possible to operate over a
wide temperature range without a heatsink. Excellent
thermal management is also achieved through the use
of the ceramic substrate and a lead-frame with a large
amount of pin connections to the board. The high
reliability and the low profile of the PKD series makes
them particularly suited for Information Technology
and Telecom (IT&T) applications with board spacing
down to 15mm (0.6 in.).
These products are manufactured using highly auto-
mated manufacturing lines with a world-class quality
commitment and a five-year warranty.
Ericsson Power Modules AB is an ISO 9001/14001
certified supplier.
