Power Modules

Ericsson has introduced a new DC/DC converter module based on the company’s innovative and proprietary power topology known as Hybrid Regulated Ratio (HRR) technology. The PKM4817LNH has been optimized for parallel operation to power 2200W boards in extreme-data-demand applications in the datacom industry.

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.
