Power Modules

PKB4313D is a new, low-profile, 12V-output, DC/DC converter module that offers up to 25 A current handling and 300 W of power to deliver tightly regulated voltages to point-of-load (POL) DC/DC regulators. Compatible with the DOSA (Distributed-power Open Standards Alliance) 5-pin eighth-brick footprint standard and offering an input range from 36V to 75V, the new PKB4313D advanced bus converter is ideal for intermediate bus conversion in ICT (Information and Communication Technologies) applications.

Offering excellent thermal capabilities, the new high-power module employs Ericsson’s leading-edge HRR technology to deliver high-power conversion across a wide input voltage range, while keeping power losses low. Combined, all these factors have resulted in a module that delivers high-efficiency power conversion with exemplary performance in thermally challenging environments. Delivering a typical efficiency that exceeds 96% with a 48 V input and 12 V output at half-load, the module also offers significantly reduced energy and cooling costs. Competitive products will typically dissipate 15% or more power at full load than the PKB4313D.

Latest technology

We use the latest technology and highest standards of quality and robustness for achieving the highest system performance.

The products are primarily designed for advanced information and communications equipment, such as radio base stations and switches/routers, but they are also used in a wide range of medical, avionics, computing, military and industrial applications.

We offer more than 500 board-mounted products for a wide variety of applications. They can be divided into:

  • DC/DC converters
  • Intermediate bus converters (IBC)
  • POL regulators
  • Power Interface Modules (PIM)
  • Board Power Management (BPM) supporting products

Every product design is the result of extensive research and development in power technology, broad application and system knowledge with a focus on design for environment and design for manufacturing, as well as efficient logistics and global support. The result is:

  • Low failure rate and long lifetime
  • Excellent dynamic load performance
  • High efficiency over a wide load range
  • Efficient thermal management

Design for Environment (DfE)

Since year 2000 we have applied a design for environment (DfE) policy in all product development projects, including removal of hazardous substances according to the RoHS directive and a continuous development of designs and solutions for lower power consumption and lowest possible total cost of ownership for the end-user.
