Digital power IC market to surge at 19.8% CAGR 8/21/2009
The worldwide digital power IC market -- including controller ICs, converter ICs, and system management ICs -- is expected to grow from more than 5 billion units in 2009 to 12.3 billion units in 2014.6A PSIP dc/dc converter achieves 15W/cm² 8/6/2009
Enpirion keeps raising the bar on its tiny PSIP (power-supply-in-package) dc/dc buck converters. The 6A EN5364QI and the 9A EN5394QI each have an input-voltage range of 2.375 to 6.6V and fit into an 8×11×1.85-mm package, achieving as much as 93% efficiency and a power density of 15W/cm².Monolithic 6A dc/dc step-down controller integrates synchronous switcher, power-output FETs 8/6/2009
Texas Instruments’ latest additions to its Swift series of power-supply ICs include point-of-load dc/dc converters in highly integrated packages. The 17V TPS54620 step-down synchronous switcher with integrated FETs comes in a 3.5×3.5-mm package and contains the control IC and power-output FETs.Lithium-battery formulation suits medical applications 7/21/2009
EaglePicher Medical Power, a supplier of batteries to manufacturers of implantable medical devices, has recently introduced a lithium-CFX (carbon-monofluoride) battery chemistry.Printable, paper-thin battery possible by year's end 7/7/2009
Aiming for a price below 10 cents, researchers from Germany claim a 1.5V battery that is thinner than a millimeter, lighter than a gram, and that could be produced cost-effectively through a printing process by the end of the year.Ultra-low-power microcontroller family brings accuracy, low power to three-phase metering 7/2/2009
Accurate, low power, and tamper proof are the key features of the new generation of smart meters that will enable the infrastructure of the smart grid.IEEE, industry players in race to help modernize smart grid 6/17/2009
Engineers and industry officials have started the clock ticking after a “historic” meeting in Santa Clara to begin to frame standards to help modernize the North American power grid, which has remained virtually unchanged for a century.POE ICs offer increased power efficiency for PDs 5/27/2009
Akros Silicon cannily plays the efficiency card—for both energy and space—with its new AS1854 POE (power-over-Ethernet) PD (powered-device) IC.Single IC integrates both drivers and controller for HB-LED lighting 5/7/2009
Most solid-state lighting applications require more electronics than just a series of HB LEDs (high-brightness light-emitting diodes) and their associated power-control circuitry. Lighting features such as communication and control and dimming, among others, require additional circuitry, including high-current drive electronics.Highly integrated power converter combines efficiency, small footprint 4/8/2009
The tiny, self-contained ENP53F8QI PwrSOC (power supply on chip) from Enpirion provides an ideal power source for electronic systems, especially in space- and power constrained systems, such as USB (universal-serial-bus) wireless data cards.EDN names winners of 19th Annual Innovation Awards 3/31/2009
EDN has bestowed its 19th Annual Innovation Awards, honoring a diverse group of electronics engineers and the ground-breaking products they have produced. The Altera Stratix IV 40-nm FPGA design team is named Innovator of the Year. Read on for a complete list of the winners.Technology squeezes the most power from solar-cell arrays 1/22/2009
National Semiconductor plans to introduce the SolarMagic chip technology, which optimizes the power output from solar-cell arrays. The company expects the chip to be useful in the management of battery packs in applications such as EVs (electric vehicles) and HEVs (hybrid EVs). Solar cells usually connect in series/parallel arrays.Electric-car development spurs investment in US battery manufacturing 1/16/2009
At last month’s Detroit Auto Show, General Motors made the long-awaited announcement that LG Chem, a Korean lithium-ion-battery-cell manufacturer, will be providing the cells for the Chevy Volt PHEV (plug-in-hybrid-electric vehicle).Precise monitoring maximizes HEV-lithium-ion-battery performance 1/8/2009
Linear Technology has been working closely with a major HEV (hybrid-electric-vehicle) manufacturer in developing the LTC6802 high-voltage, precision battery-stack-monitor chip.MIT researchers claim 50% increase in solar-cell output 1/8/2009
A team of physicists and engineers at MIT (Massachusetts Institute of Technology) claims that sandwiching a solar cell between an antireflective coating on the front and a combination of reflective coatings and a diffraction grating on the back can increase the cell's output by as much as 50% for a 2-micron-thick cell.ADVERTISEMENT
