Low-profile 5A power module targets telecomms & SSDs
Designed specifically for height-constrained telecomms, industrial and SSD applications, an integrated switching power module has been unveiled by Microchip. The MIC45404 integrates inductors and passive components in a 10x6x2mm thermally-enhanced package, which saves space, simplifies board design and eliminates concern over passive components that may introduce unexpected EMI.
Immediately operate & evaluate a complete power system
Allowing power system designers to immediately begin operating and evaluating a complete power system solution featuring the industry’s thinnest, highest performance, highest density power components, Vicor announces its AC to PoL Development Kit (ACPoL DKit).
Digital hybrid PWM controllers are PMBus compatible
Offering PoL conversions for FPGAs, DSPs, ASICs, processors and general purpose system rails, Intersil has launched two digital hybrid DC/DC controllers. The ISL68200 with integrated MOSFET drivers and ISL68201 with PWM output simplify power supply designs for data centre routers, servers and storage, as well as wireless infrastructure equipment.
Buck converter reduces system noise & saves space
Texas Instruments has announced a 2.2MHz, dual-channel synchronous buck converter which reduces EMI and high-frequency noise in high-voltage DC/DC step-down applications such as automotive infotainment and high-end cluster power-supply systems. The LM5140-Q1 includes dual outputs with phase interleaving and is offered in wettable flank packaging that enables post-solder visual inspection to speed manufacturing.
100V MOSFET reduces voltage ringing and EMI
Delivering improvements in efficiency, reduced voltage ringing and lower EMI are promised for power supplies, motor drives and other applications requiring a 100V MOSFET. Fairchild has added the FDMS86181, 100V, shielded n-channel MOSFET to its PowerTrench range.
Digital PoL regulators enable FPGA development platform
Infineon Technologies has announced that its digital PoL DC/DC regulators with full PMBus capabilities are featured in the Kintex UltraScale development board. A key driver for the design flexibility of the board is the superior PMBus connectivity of the company's IR3806x family. Configurations can be stored in internal memory and PMBus commands allow run-time control, fault status and telemetry.
Storing energy from floating wind farm in batteries
Norwegian oil group Statoil said it would store energy from a Scottish floating wind farm on a powerful battery storage system, in a pioneering pilot project. The system's one megawatt-hour Lithium battery capacity corresponds to that of "more than two million iPhones," Statoil said in a statement, making it one of the world's most ambitious projects in the field.
Laser method creates micro energy units
In the race to design smaller handheld devices and smartphones, a key factor is decreasing the sizes of components. As the demand for thinner and lighter microelectronic devices increases, manufacturers often are limited by how oddly shaped the energy sources must become to make them conform to the smaller space. Now, researchers at the University of Missouri, have developed a method of transferring an energy source to virtually any shape.
Agreement to provide power supplies for the APG-83 SABR
Milpower Source signed a long term agreement with Northrop Grumman to provide power supplies for the APG-83 Scalable Agile Beam Radar (SABR). Milpower Source implemented innovative technology providing low noise, low weight and high efficiency power supplies for the program.
Energy input predicts molecular behaviour
The world within a cell is a chaotic space, where the quantity and movement of molecules and proteins are in constant flux. Trying to predict how widely a protein or process may fluctuate is essential to knowing how well a cell is performing. But such predictions are hard to pin down in a cell's open system, where everything can look hopelessly random. Now physicists at MIT have proved that at least one factor can set a limit, or bound, on a give...
