The PKM 4000D series of high efficiency DC/DC con-
verters are designed to provide high quality on-board
power solutions in distributed power architectures used in
Internetworking equipment in wireless and wired com-
munications applications. The PKM 4000D series uses
patented synchronous rectifi cation technology and
achieves an effi ciency up to 89% at full load. Included as
standard features are output over-voltage protection, input
under-voltage protection, over temperature protection, soft-
start, output short circuit protection, remote sense, remote
control, and output voltage adjust function. These converters
are designed to meet high reliability requirements and are
manufactured in highly automated manufacturing lines and
meet world-class quality levels.
Ericsson Power Modules is an ISO 9001/14001 certified
supplier.
