required
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 use a ceramic substrate with thicklm tech-
nology and a high degree of silicon integration. That,
together with the electrical design using synchronous
rectication gives good thermal management, high
reliability and high efciency.
The high efciency makes it possible to operate over a
wide temperature range without a heatsink. At forced
convection cooling >200lfm (1m/s), the PKD units
E
PKD 4000 SI
can deliver full power up to +70°C ambient tempera-
ture. The high reliability and the low prole of the
PKD series makes them particularly suited for Infor-
mation 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 ve-year warranty.
Ericsson Microelectronics AB has been an ISO 9001
certied supplier since 1991. For product program please
