PKM 4000 C Series
E
The New PKM 4000C series of high power high
efficiency DC/DC converters are designed to provide
high quality on-board power solutions in distributed
power architectures used in Internetworking
equipment in wireless and wired communications
applications. The PKM 4000C series has the new
industry standard quarter brick footprint and pinout
that can accomodate 2 or 4 output pins and is only
8.7mm high in the non-baseplate design. This
makes it extremely well suited for narrow board
pitch applications. The PKMC Series uses patented
synchronous rectification technology and achieves
an efficiency up to 92% at full load. The series is
available in non-baseplated and baseplated versions.
Ericsson's PKM 4000C Series addresses the power
needs for all industries and are manufactured in highly
automated manufacturing lines meeting world-class
quality levels. Ericsson Power Modules is an ISO
9001/14001 certified supplier.
