The case for on-board voltage monitoring IP
As Cadence’s Bob Salem explains, advances in mobile and Internet of Things (IoT) applications are challenging chip designers to deliver increasing performance and longer battery life.
The capacitive power supply that promises 99% efficiency
A patented technique using switched capacitor charge pumps to produce small, efficient power supplies and inverters could spell the end for transformer-based systems. Sally Ward-Foxton reports.
Quick-destructing battery could power 'transient' devices
Reza Montazami, an Iowa State University assistant professor of mechanical engineering and an associate of the U.S. Department of Energy's Ames Laboratory, has been working on transient technology for years. The latest development from his lab is a self-destructing, lithium-ion battery capable of delivering 2.5 V and dissolving or dissipating in 30 minutes when dropped in water. The battery can power a desktop calculator for about 15 minutes.
Power supply exceed DOE's energy efficiency requirements
The TE40 series 40W power supplies from SL Power Electronics has been added to the line of Level VI+ external power solutions for test and measurement applications. The TE40 has been specifically designed for the power rigours of test and measurement and industrial devices that require low noise and robust performance.
Li-ion batteries made of solid materials improve safety
Researchers at ETH Zurich have developed a lithium-ion battery made entirely of solid material: it contains neither liquids nor gels. The battery cannot ignite, even at very high temperatures, giving it a safety advantage over conventional batteries. In addition, they allow new forms of battery design.
Nanoscale secrets of rechargeable batteries
Better batteries that charge quickly and last a long time are a brass ring for engineers. But despite decades of research and innovation, a fundamental understanding of exactly how batteries work at the smallest of scales has remained elusive.
Regulated 10W DC/DC converters offer wide input range
Designed for applications where wide input range and accurate regulation are key factors, the RP10-A and RP10-AW series DC/DC converters have been unveiled by RECOM. Typical applications for the converters include battery-powered systems, instrumentation, or distributed power architectures in telecomms or industrial electronics.
Wide creepage transistors offer superior arcing resistance
STMicroelectronics has introduced a portfolio of TO-220 FullPAK (TO-220FP) wide creepage power transistors, including the world’s first 1,500V super-junction MOSFET in this new important arcing-resistant package.
200mA LDO regulator suits portable & flexible electronics
Supplied in a minuscule 0.47x0.47x0.2mm CSP, a 200mA LDO regulator has been introduced by STMicroelectronics for wearable and portable devices and flexible electronics such as multifunction connected smart cards. The LDBL20’s bumpless STSTAMP package breaks through the minimum I/O-area and height limitation imposed by the diameter of traditional flip-chip solder bumps, enabling unprecedentedly small footprints and low mounted heights.
Converter modules provide solutions for wayside communication
The C600 series of DC/DC and AC/DC converter modules has been introduced by Schaefer. The highly-reliable, compact and ultra-rugged 3U design uses industrial-grade components and provides a high-density, space saving solutions for wayside signal and communication installations globally. These units are ideal for redundant systems with two units per 19” sub-rack.
