Linear Technology Corporation has announced the LTC3882, a dual-output multiphase synchronous step-down dc-dc controller with a serial digital interface. The LTC3882 uses leading-edge modulation voltage-mode control for excellent transient response and operates with very low DCR (0.25 milliohm) inductors, enabling higher efficiency and up to 40A per output phase. Compatible power train devices include DrMOS, power blocks or discrete FET

The ultralow-density, ultrahigh surface area bulk material with an interconnected nanotubular makeup could be used in energy storage and conversion, thermal insulation, shock energy absorption and high energy density physics. The three-dimensional nanotubular network architecture developed by the team also opens new opportunities in the fields of energy harvesting, catalysis, sensing and filtration by enabling mass transport through two independent

It’s been two years now since the first buyers got their hands on a Tesla Model S, and despite some long-term reliability concerns, the Model S has been universally praised for building not just a great EV, but a great car as well. As is typical in the auto industry though, Tesla isn’t resting on its laurels, and the electric

Energy storage systems are a boon for generators, especially renewable energy generators, as they can regulate their energy supply while maintaining grid discipline. But energy storage systems can be of great advantage to large consumers such as industrial units and commercial buildings to keep their power bills in control. Sharp has launched an energy storage system aimed at large individual

In what could be the last few weeks of the Australian Renewable Energy Agency (ARENA), some of its largest investments are now beginning to take shape. Australia’s largest solar power project, with a generation capacity of 102 MW, received its first shipment of solar photovoltaic modules. ARENA has invested about A$167 million in the project while the New South Wales

Graphene is a super material that is 100 times stronger than steel, conducts electricity better than copper, and is more flexible than rubber. It’s used in electronics but it’s prohibitively expensive to produce – so David Mitlin of Clarkson University, New York has discovered a way to replicate at least some of its properties with cheap hemp fiber leftover from

Google has announced the finalists of this year’s Google Science Fair and the line-up is impressive. But among the 15 inventions designed to make the world a better place, Cynthia Sin Nga Lam’s submission is definitely a major standout. Concerned about the millions of people living without energy and water, the 17-year-old student scientist from Australia built H2Pro – a

16-year-old Samuel Burrow has found a way to scrub the world clean of toxic pollution using materials found in sunscreen and pencils! The teenager developed a white, smog-busting mixture of titanium dioxide and graphene oxide that can be applied to internal and external surfaces like paint. His solution is strong, efficient, and cheap – and it uses simple ingredients commonly

Claimed as the smallest bidirectional 18-V, 5-A protection switches, with high power efficiency, TI intends these devices to be used in portable and adapter-powered devices, and enterprise and client solid state drives (SSDs). TPS25940 and TPS25942 integrated circuits include back-to-back FETs to provide bidirectional current control, while reducing system size by 50% compared to discrete solutions. These smart eFuse ICs

The FAA tests were conducted because many airlines are replacing paper charts with laptops and tablet computers and the regulator wanted to see what would happen if one of their rechargeable lithium-ion battery cells ignited. In one test, the cockpit filled with smoke thick enough to obscure instruments and vision out the window for about five minutes. The findings, posted
