Quad 4-A Regulator Offers Parallel Output Flexibility
Linear Technology’s LTM4644 µModule (micromodule) combines four switching regulators to support most if not all the power needs of modern digital systems in one surface-mount package.
DC-DC Converters Aim For Efficiency 1
Today, dc-dc converter efficiency is becoming the keyword for new designs because of the desire to reduce power consumption both in battery-based and embedded systems. This article covers describes both types of dc-dc converters as well as use of GaN transistors and design support to improve dc-dc converter performance.

Solar Power Warms To Distributed PV Systems
Tutorial on Distributed Photovoltaic Systems, which combine grid-tie and battery-backup features.
SEGIS Pushes Photovoltaics Into The Grid
The U.S. Department of Energy SEGIS (Solar Energy Grid Integration Systems) pogram aims to support industry in developing new technologies for distributed power.
New Devices Embrace Energy Efficiency
Power-industry veteran Sam Davis reviews a broad range of electrical efficiency issues from a design standpoint.
Li-Ion Battery Protection ICs
The simplest protection method for battery packs is a fuse that opens if the system draws excessively high current. A more complex protection circuit is found in some battery packs. The battery-protection ICs prevent excessive current, which could lead to
Batteries 101: From Nickel To Lithium And Beyond
Virtually all battery-based power-management designs depend on the associated battery, so design starts by picking the specific battery type. The battery may be the non-rechargeable primary type or the rechargeable secondary type. The most widely used rec
MIT, TI Develop Energy-Efficient Microchip
Researchers at the Massachusetts Institute of Technology (MIT) and Texas Instruments have developed a topology that shows promise for ultra-low-power systems with a chip design that can be up to 10 times more energy-efficient than present technology. The
Switch-Mode ICs Promote Efficient Power Management, Part 2: DC-DC Controllers And Converters
Switch-mode ICs play a dominant role in optimizing the efficiency and minimizing the size of power-conversion subsystems used in consumer, computer, and industrial equipment.
Switch-Mode ICs Promote Efficient Power Management, Part 1: Switch-Mode Fundamentals
A switch-mode converter circuit uses a controlled power semiconductor switching technique along with an inductor, transformer, or capacitor as an energy-storage element to transfer dc power from its input to its output. In a basic switch-mode converter, a
Shrewd Thermal Management Helps Defeat the Heat
Despite great strides made by electronic system designers in developing products that perform sophisticated tasks, engineers may encounter performance-limiting factors beyond electronic circuitry—like thermal management. Even if
A court decision could determine the future of the competing architectures as well as that of digital powersupply management.
IEEE To Push For More Engineers And Educators Worldwide
While the demand for engineers has waxed and waned over the past half century, the need seems to be growing again. At least, that’s the premise of Meeting the Growing Demand for Engineers and Their Educators 2010-2020, a conference that will be held in
AeA Announces Job Growth Despite Decline In U.S. Competitiveness
Within a few days of each other, AeA (formerly the American Electronics Association) released two reports—one with good news and the other with bad news. The good news is that the United States’ high-tech industry followed 2005’s turnaround with
