PKN 4000 I
50 W DC/DC power module
48 V input series
The PKN 4000 I series of DC/DC power modules are
intended to be used as distributed power sources in
decentralized 48/60 V DC power systems. The PKN
series use a ceramic substrate with thickfilm technolo-
gy and a high degree of silicon integration. That to-
gether 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. At forced convection cooling
>200 lfm (1 m/s), the PKN units can deliver full
power up to +80°C ambient temperature. The high
reliability and the low profile of the PKN series makes
them particularly suited for Information Technology
and Telecom (IT&T) applications with board spacing
down to 15 mm (0.6 in.).
These products are manufactured using highly
automated manufacturing lines with a world-class
quality commitment and a five-year warranty.
Ericsson Microelectronics AB has been an ISO 9001
certified supplier since 1991. For a complete product
program please reference the back cover.
