Buck-boost controller and charger combo simplify USB-C, power-delivery designs
As portable devices add new technologies such as 5G connectivity and 4K video, many are changing from single-cell to two-series (2S) cell architectures. With this change comes the need for higher power delivery via USB-C PD and higher-power charging (25W or higher). Maxim Integrated Products has released the MAX77958 USB-C PD controller and the MAX77962 […]
Next-generation shielding may absorb electromagnetic interference rather than reflect it
Engineers trying to shield RF-sensitive circuitry a few years from now may have the option of using material that absorbs RF energy rather than just reflecting it. So say researchers at Drexel University and the Korea Institute of Science and Technology. They are researching a class of material called MXenes, and more specifically, titanium carbonitride […]
Boosting performance in 48-V power distribution
New ways of routing power around circuit boards bring more efficiency and fewer thermal problems. Phil Davies | Vicor Corp. Power distribution networks (PDNs) are the backbone of any power system. As system power demands rise, traditional PDNs are under tremendous pressure to deliver enough performance. There are two main ways to improve PDN impact […]
Automotive-qualified multilayer varistors combine bi-directional overvoltage circuit protection, broadband EMI/RFI filtering
AVX Corporation has released a new series of automotive-qualified multilayer varistors (MLVs) specially designed to exhibit lower breakdown- and clamping-voltage to working-voltage ratios than other standard varistors. Comprised of zinc-oxide-based (ZnO-based) ceramic semiconductor devices with nonlinear, bidirectional voltage-current (V-I) characteristics similar to those of back-to-back Zener diodes, but with greater current and energy handling capabilities […]
