Researchers say a newly tested method for producing super dense, defect-free, thin polymer films is the fastest, most efficient method ever achieved and it may dramatically improve microelectronic storage capabilities, such as those in computer memory sticks. In the February 20 issue of the journal Science, researchers at the University of Massachusetts Amherst and their colleagues at the University of California Berkeley report
Accepting an input from 85 VAC to 260 VAC, the 15-degree narrow-beam PAR30A LED bulb from LED is made up of five 3-W, high-power LEDs and replaces filament-based 75-W incandescent or halogen bulbs.
Addressing the higher currents needed by the next generation of high brightness LEDs, the RCD-24-1.0 and RCD-24-1.2 solid-state lighting drivers (SSLD) from Recom are available in versions delivering up to 1,200 mA. The 22 × 12.5 × 8.5-mm devices require no external components, reducing the circuit footprint by up to 50%. Features include short circuit protection and thermal shutdown as well as independent PWM and Analog linear dimming inputs
Kazakhstan announced Thursday it was pulling out of the Central Asian power grid to protect its energy supplies, a move that forced rolling blackouts and electricity rationing on Kyrgyzstan, its tiny, power-starved neighbor. Kazakhstan said it had to withdraw from the power grid because Tajikistan was taking more energy from the grid than it was producing.
Leadis Technology announced that its proprietary LED-Sense temperature sensing and compensation engine, implemented in the LDS8160, is now available for licensing to third parties as an embedded, stand-alone IP block. This IP engine, suitable for enhancing the performance of LED driver, light management unit, and power management unit ICs, directly measures the junction temperature of an LED in the system at its
Enabling software and mechanical engineers to work together to design, test, and modify custom motion algorithms, Danaher Motion’s MechaWare 3.0 mechatronic toolkit seamlessly integrates mechanical systems and control software design. The product includes capture, logging, and visualization tools that allow mechanical, I/O, and software data to be integrated into one measurement environment. The toolkit delivers
Designed for PET scanners, communication systems, and advanced video equipment, Analog Device’s AD8264 quad-channel VGA (variable-gain amplifier) demonstrates a 24-dB gain range. The 40-lead LFCSP-packaged component has auxiliary differential ADC drivers operating with ADI’s data converters. The device’s pinout provides single-ended output taps directly from the VGAs, which have a -3-dB bandwidth of
Targeting industrial, scientific research, and quality assurance applications, Omega Engineering’s OM-SQ2020 Series portable data loggers have 8 true differential or 16 single-ended universal analog inputs, plus 2 high voltage, 4 pulse, and 8 digital event/state inputs. The devices work with thermistors, thermocouples, 2-, 3-, or
Presenting an adjustable 24-VDC output voltage, Carlo Gavazzi’s SPD Series 3-phase switch-mode power supplies deliver outputs of 120 W, 240 W, 480 W, and 960 W. The DIN rail-mountable devices exhibit up to 93% efficiency, input voltage ranges from 340 VAC to 575 VAC and 480 VAC to 960 VAC, and
Exhibiting typ. phase noise of -120 dBc/Hz at 10-KHz offset, Crystek's CVCO55CC-1700-1700 VCO functions at 1,700 MHz with a control voltage range from 0.3 V to ~4.7 V. The 0.5” × 0.5” SMT component offers typ. output power of 2.5 dBm, input voltage of 5 V, max. current consumption of 25 mA, and typ. second
Said to draw <1/10 of the power of a typical PC being used as a home server, Marvell Semiconductor’s SheevaPlug development kit is small enough to plug directly into a wall socket. The platform uses a Kirkwood embedded processor based on an embedded 1.2-GHz Sheeva CPU equipped with 512-MB Flash and
Optomec announced today that its Aerosol Jet system has been used to fully print Carbon NanoTube (CNT) based Thin Film Transistors (TFT) with operating frequencies over 5 GHz. The work was conducted in collaboration with the University of Massachusetts and Brewer Science. The results were recently published in APPLIED PHYSICS LETTERS (93, 243301 2008) with a paper titled “All [aerosol] jet-printed carbon nanotube thin-film transistor on a polyimide substrate with an ultrahigh operating frequency of over 5 GHz.”
Certess today announced Certitude-C, the next generation of its functional qualification software product for companies developing SoCs or integrating intellectual property (IP) blocks using C. Certitude-C adds support for ANSI C to the capabilities of the original product, allowing functional qualification of both reference models and high-level representations of designs written in C.
With a 1.5 V rating for both Read and Write operations, a series of I2C EEPROM devices from Microchip is purported to have the lowest operating voltage available on the market. Operating current is below 400 microamperes. The devices feature an operating frequency of 100 kHz at 1.5 V, and are available in densities of
