DC-DC Converter and IC Markets Identified
The real changes occurring in the dc-dc converter module and IC market are at the power architecture and advanced materials levels. In fact, the emergence of the Dynamic Bus Architecture (DBA) will be one of the most significant developments in the power supply industry in 10 years. These developments are highlighted in a new global analysis from Darnell Group, "Dc-dc Converter Modules and ICs: Market Forces, Power Architectures and Technology Developments."
The DBA is already being designed into some high-end systems, and widespread adoption is expected in the next few years. Most of the distributed power architectures being implemented today, and certainly future systems, include some form of digital power management and control. The evolution of the Intermediate Bus Architecture (IBA) – from the Central Control Architecture (CCA) to the emerging Dynamic Bus Architecture – is in part due to system demands that digital power management can address effectively.
The DBA makes use of a Digital Bus Converter (DBC), which is able to dynamically optimize its intrinsic efficiency, along with overall system efficiency, and can be controlled and monitored. In addition, the emergence of the DBC threatens to obsolete all of today’s analog bus converter products, including unregulated, semi-regulated and even regulated devices.

With global economies slowly recovering from the recession, companies are looking to keep costs low and optimize the equipment they already have. Advanced materials, such as Silicon-carbide (SiC) and Gallium-nitride (GaN), are slowly becoming more cost-effective. And as costs come down, these materials are likely to improve converter efficiencies and enable higher operating frequencies and smaller converter sizes.
The 94-page report also looks at how close "on-chip power supplies" (such as Power-Supply-in-Package

It also examines how standards are driving sales in digital power, dc powering of buildings, and Power-over-Ethernet. Company-led organizations are pushing standards and product certifications that are expected to lead to rapid commercial adoption of the newer technologies, while further refining existing ones. The report includes an overview of these standards, along with the companies participating in their development.
Additional sections consider the current dynamics in the traditional dc-dc module market, including bricks, bus converters, point-of-load converters and "power blocks." These mainstays of the dc-dc converter market are still holding their own against the trend toward IC solutions, with a focus on power density, thermal issues and packaging. Along with dc building power, photovoltaics and light-emitting diodes (LEDs) are likely to provide sales for power supply manufacturers going forward.
Finally, of the nearly 180 companies mentioned in this report, 24 are discussed in more detail in an overview of the major dc-dc converter module and PwrSoC and PSiP manfacturers. The opportunities for dc-dc converter module and IC makers are greater now than they have been in years, due to emerging applications, new power architectures, advanced materials and components, and energy efficiency standards. The power supply industry can take advantage of these developments, knowing that additional markets are likely to arise in the future.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
