Ericsson’s high-density and high-efficiency power supplies for distributed power architectures are the building blocks 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 are also used in a wide range of medical, avionics, computing, military and industrial applications.

Ericsson offers more than 500 power supply products for a wide variety of applications. They can be divided into:

• Board-mounted products, such as DC/DC converters, intermediate bus converters and point-of-load regulators
• Embedded and stand-alone products for selected applications, such as power boards and power supply units.

All products are developed to meet customer requirements on energy efficiency and sustainability as well as quality and total cost of ownership.

Ericsson works actively with its customers to ensure the optimum solution for every application. In addition to the products in the existing portfolio, Ericsson can offer solutions that are tailored to meet specific customer and application requirements.

General Specifications:

• Output voltage range: 0-150 V
• AC/DC output power range: 5-150 W
• DC/DC output power range: 5-1000 W
• DC/DC input voltage range: 5-400 V

The customer is involved in each step of the product development process, from the first pre-study to the delivery of the approved products and follow-up. This ensures that the product exactly meets the specified technical and performance requirements so the customer can be confident the end-product will support and improve their business and brand value.

Ericsson has one of the most extensive power supply offerings on the market, with more than 500 different products for a wide variety of applications. And since 1983, more than 60 million units have been supplied to customers worldwide.

Ericsson drives its own technology development through extensive R&D, and supports industry-wide collaborations by participating and driving standardization in bodies such as the Distributed-power Open Standards Alliance (DOSA), the European Power Supply Manufacturer Association (EPSMA), the High Density Packaging User Group (HDP User Group), the Power Management Bus Implementers Forum (PMBus), the Point of Load Alliance (POLA) and the Power Sources Manufacturers Association (PSMA).

The reliability and availability of all electronic equipment is underpinned by the reliability of its power supply. Ericsson Power Module products, used throughout Ericsson’s own equipment and systems, utilize the latest technology and automated manufacturing processes to provide high reliability, robustness and a level of performance that results in low total cost of ownership.

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.

Quality assurance is achieved through Ericsson’s commitment to securing supplier quality, closed loop corrective actions towards zero defects and employee training.

The result is:

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

Since year 2000 Ericsson Power Modules has 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. This include restriction of hazardous substances, with special focus on lead-free components, lead-free manufacturing processes, halogen-free printed circuit boards and components and products that meet the requirements in customers lead-free manufacturing processes. Products and processes also comply with Ericsson lists of banned and restricted substances, which include the six restricted substances in the RoHS directive but also an extensive list of other substances that are either banned, restricted or under observation due to environmental regulations or concerns.

RoHS directive
The RoHS directive requires that, from July 1st 2006, new electrical and electronic equipment (EEE) put on the market does not contain more than the permitted levels of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE). The directive apply to the final end-user products e.g. IT and telecommunications equipment, that fall within the scope of the directive. From a legal point of view, components and sub-assemblies, e.g. DC/DC power modules, are not covered by the directive but are required by the equipment manufacturers to meet the requirements in the RoHS directive. DC-DC power modules meet the requirements if the concentration values of hazardous substances do not exceed 0.1% by weight in homogeneous materials for lead, mercury, hexavalent chromium, PBB and PBDE and 0.01% by weight in homogeneous materials for cadmium.

Ericsson Power Modules' products are compatible with the relevant clauses and requirements in the RoHS directive. Products intended for surface mount assembly will also comply with high-temperature lead-free reflow soldering processes according to IPC/JEDEC J STD 020C and products intended for through-hole mount assembly will comply with lead-free wave soldering or manual soldering processes.

Efficiency and energy consumption
Efficiency and energy consumption are two of the most important environmental factors in the end-user equipment. In recent years the industry has learned that energy consumption in the operation of Information and Communication Technology equipment is the most critical factor relating to environmental impact and total cost of ownership. Ericsson Power Modules' DfE policy drives the design and development of high efficient DC/DC power modules that will decrease the energy consumption of the end-user equipment resulting in lower environmental impact and life cycle cost. This does not only affect the energy bill but also the design, dimensioning and cost of other parts of the complete installation, such as cooling fans and air conditioning, heat sinks, real estate requirements, power supplies and battery back-up capacity, etc. Higher efficiency in the DC/DC power modules will contribute to lower total cost of ownership for the end-user and a more resource efficient society.
