Is digital power moving forward?

It is now several years since commercial products with 'added digital performance' aiming to revolutionise the power industry have been around in the marketplace. At a time when energy efficiency and power consumption are becoming more strategic than ever, the debate around how "digital power" will change the face of the world has never been so intense. Energised by the high marketing buzz surrounding 'the new power revolution', thousand of papers have often strongly expressed the details and benefits of implementing such technology. However, a certain market perception gives the feeling that behind the noise generated by the media, digital power seems not to have moved as fast as expected. Wrong perception or reality?

From digital confusion to digital conversion

It is now several years since commercial products with 'added digital performance' aiming to revolutionise the on-board power industry have been around in the marketplace. The debate around how such products will change the face of the world has never been so intense, resulting in a certain kind of confusion.

Digital DC/DC converter family integrates PMBUS connectivity

Able to work with any type of power converter, PMBus is a major success story. Its simple SMBus-based two-wire hardware interface is similar to and generally compatible with I2C, while the improved signaling protocols assure greater robustness. As a result, system designers can easily implement power management strategies that range from voltage sequencing or multi-voltage logic devices to monitoring and controlling entire systems using a uniform approach that has minimal impact upon resources.

Digital DC/DC converter benefits in MicroTCA power modules

Micro Telecommunications Computing Architecture (MicroTCA) is a relatively new architectural specification for Information and Communications Technology (ICT) and industrial equipment intended for relatively small, low power applications where it can be more cost effective than other architectures. The key power assembly in MicroTCA is called the 'MicroTCA power module' , which, by its own definition has to deliver and secure the power required by Advanced Mezzanine Cards and other accessories that plug-into the MicroTCA enclosure.

Batteries worldwide celebrate the arrival of the world's most energy friendly microcontrollers

The explosion in use of battery operated electronics is followed by the need for the battery to last longer for convenience, environmental and cost reasons. At the same time, applications become more and more complex and demand higher performance of the microcontroller, making the challenge of designing systems for low power even more difficult. This white paper looks at Energy Micro's EFM32 microcontroller family, which it says has an energy consumption many times lower than any other microcontroller family today, whether you benchmark with leading 8, 16 or 32 bit microcontrollers.

Network Technology for Embedded Computing

Networks are gaining importance in all disciplines of embedded computing: At the high-end, multi-processor systems need high-speed networks for interconnectivity and feeding in data. The scope of this paper are major trends in Ethernet network technology and how network technology, both hardware and software, is implemented in high-end embedded systems. As practical examples, embedded form factors CompactPCI and MicroTCA are shown at 10 Gigabit/s speed for switching and packet processing. This paper concludes with a practical look into the components of a switching platform for embedded products.

3E-Enhanced performance, Energy management and increased End-user value with digital POL regulators

Ericsson Power Modules' new digital POL (point-of-load) regulators establish an innovative approach to reach the goals of end-user value, flexibility and system performance. These new power supply products contain several unique concepts and features spanning the disciplines of mechanical packaging, electrical design, control loop algorithms, power system architecture, power and energy management tools and logistics during system manufacturing and field support.

3E-Enhanced performance, Energy Management and increased End-user value with digital DC/DC converters

Ericsson Power Modules has recently introduced a comprehensive set of products that establish an innovative approach to the goals of end-user value, flexibility and system performance. These new products contain several unique concepts spanning several disciplines in circuit and system design, all focused on optimizing performance, flexibility and value for the end-user. Ericsson Power Modules refers to the high level end-user benefits of this product approach as "3E". Read more in this white paper.

System Verilog & OVM: Mitigating verification challenges and maximising resusability

This white paper from Applied Micro looks at the challenge of verification – a nightmare for engineers with the increasing requirements and complexity of the design – and mitigating the complexity of a verification environment with the increasing complexity of design verification. System Verilog, along with its library of classes – OVM, provides a platform to face this challenge.

Long term storage of electronic components

Long term storage, particularly of last time buy components, has been proposed as one solution to the problem of component obsolescence. The Alter Technology Group is in a unique position to report on this concept and advise the best way to manage long term storage and eliminate associated reliability problems.

Counterfdeit components and acoustic microscopy

This white paper from Alter Technology Group considers how the encapsulants used by semiconductor manufacturers may be identified and changes or variations detected - and will look in detail at encapsulants, and the potential hazards to system reliability. The paper explains the principles of CSAM and illustrates how these are applied in nondestructive testing, failure analysis and how the CSAM compliments radiographic or x-ray inspection. The limitations of CSAM are also reviewed. The paper also describes the results of Alter UK's research to date into plastic encapsulants and suggests how this work may be taken forward in the fight against counterfeiters.
