Bosch, GS Yuasa, and Mitsubishi Corporation Working On Next Generation Lithium-Ion Batteries
Robert Bosch GmbH and the Japanese companies GS Yuasa International Ltd and Mitsubishi Corporation have agreed to work together on the next generation of high-performance lithium-ion batteries. These batteries are fundamental for future forms of mobility, such as plug-in hybrid or all-electric vehicles. The companies aim to use advanced cell management and progress in electrochemistry and materials to significantly increase energy content. This w...
High Voltage Power Supply Excellence
HiTek Power has just published the second edition of the product catalogue which was first launched last year. The new 72-page colour HiTek Power catalogue gives a good insight into the company, highlighting its custom high voltage design expertise, design and engineering skills, its modern 34,000 sq ft, cross-functional manufacturing facility, as well as detailing the quality power supplies it offers in the very specialist field of high voltage.

Premier Magnetics announces its POL-HX Series of switch-mode transformers designed to complement Power Integrations’ TOPSwitch-HX Family of EcoSmart, integrated off-line switcher ICs. The Premier Magnetics POL-HX Series is currently available in 21 models – most accommodating a universal AC input range of 85 to 265 V ac.
Z+ Series of Programmable Power Supplies includes 600W models
TDK Corporation announces that 600W models have been added to its TDK-Lambda Z+ Series of programmable DC power supplies. Complementing the Z+200, Z+400 and Z+800 ranges, these 600W programmable power supplies offer the same superior features and carry a 5-year warranty. Addressing the need for high quality bench-top power supplies for the R&D environment, the TDK-Lambda Z+600 range shares the same dimensions as the other Z+ ranges and thus offer...
CUI Announces IEC 60601-1 3rd Edition Certifications for Medical Power Supply Line
CUI today announced its range of medical power supplies has received IEC 60601-1 3rd edition medical safety certifications. The certification covers 17 product families ranging from 15 W to 400 W, easing compliance for medical device engineers.
Microchip’s new op amps extend battery life with exceptionally low power consumption
Microchip announces a new nine-member low-power, general-purpose operational amplifier family—the MCP647X/8X/9X. These op amps provide among the industry’s best power consumption for a given gain-bandwidth product, including low quiescent current, to extend battery lifetimes. Additionally, they have exceptionally low leakage current over temperature, up to 125°C, which reduces errors in applications such as sensor conditioning.
Power-One Announces New Open-Frame Products
Power-One today announced the expansion of ABC and MBC families of open-frame products, adding ten new models to the portfolio. The ABC family of industrial open-frame power supplies is now available from 40W to 400W and offers high convection ratings and industry-leading power density.
40V, 2A Synchronous Buck-Boost DC/DC Converter Offered in High Temperature H Grade & High Reliability MP Grade
Linear Technology announces the high temperature H-grade (-40°C to 150°C junction temperature) and high reliability MP-grade (-55°C to 150°C) version of the LTC3115-1 in a 20-lead thermally enhanced TSSOP package. The LTC3115-1 is a synchronous buck-boost converter that delivers up to 2A of continuous output current from a wide range of power sources from single-cell Li-Ion to 24V/28V industrial rails to 40V automotive inputs.
Ultra-Compact High Efficiency Power Supplies for Automotive Applications
ROHM has announced the development of compact, high efficiency power supplies designed to drive DDR memory, microcontrollers, and other components in car applications. The BD905xx series integrates a phase compensation circuit and feedback resistor, reducing the number of external parts considerably compared with conventional power supply ICs. This simplifies design load and contributes to end-product miniaturization.
Will graphene supercapacitors be the best?
Black magic has a new meaning. It is the sub-optimal way most supercapacitors rely on soot from burnt coconut shells and some homespun trickery. The soot is deposited on something akin to cooking foil and that often has the 40 micron thickness of lithium-ion battery electrodes ten years ago, before they were optimised.
