Safety Approvals
Design for Environment
DC/DC converter
Input 36-75 Vdc
Output up to 40A/100W
The PKJ 4000E series of 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 PKJ 4000E series has industry standard half brick
footprint and pin-out and is only 8.5 mm (0.33 in) high.
This makes it extremely well suited for narrow board pitch
applications with board spacing down to 15 mm (0.6
in). The PKJ 4000E series uses patented synchronous
rectification technology and achieves an efficiency up to
89% at full load. Ericsson's PKJ 4000E series addresses
the emerging telecom market for applications in the multi-
service network by specifying the input voltage range in
accordance with ETSI specifications.
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.
