Buck-boost LED driver topology is designed for low EMI
Of the commonly-used step-up and step-down topologies, those that produce low EMI are the most desirable for automotive LED driver circuits, says Keith Szolusha, applications engineering section leader, Linear Technology.
Wireless charging - past, present and future
Wireless charging of portable devices does much more than just getting rid of the cables, explains Meng He, executive business manager, Maxim Integrated.
Smart approaches for smart energy
Developments in low power for the Internet of Things (IoT) have led to the emergence of consortia that develop and promote low power protocols for wireless devices. By Josh Mickolio, product manager, RF and wireless, Digi-Key.
Spin of electrons could create energy efficient electronic devices
A team of researchers, led by a group at the University of California, Riverside, have demonstrated for the first time the transmission of electrical signals through insulators in a sandwich-like structure, a development that could help create more energy efficient electronic devices. Conventional electronic devices rely on the transport of electrons in a semiconductor such as silicon.
Reshaping the future for autonomous cars
The Goodyear Tire & Rubber Company has revealed two innovative new concept tires at the 86th Geneva International Motor Show that could literally reshape the future for autonomous cars. The concepts: the spherical-shaped Eagle-360 - a future-oriented tire - was designed with key features of maneuverability, connectivity and biomimicry for autonomous mobility, while the IntelliGrip, featuring advanced sensor and treadwear technology, is a solu...
DC power supplies for a host of applications
For applications requiring a compact, efficient, high performance programmable DC power supply, there are a wide range of 3kW to 150kW DC power supplies available from Lab-Power. The front panel control features operation with variable voltage and current control which can be set and displayed on the high visibility display. In addition to voltage and current, power and resistance can also be displayed.
Gate drivers provide switching for power MOSFETs or IGBTs
The DGD21xx series of six half-bridge and six high/low-side 600V gate drivers introduced by Diodes Incorporated provides a simple means of switching power MOSFETs and IGBTs in half- and full-bridge configurations. Target applications include driving motors in white goods, industrial automation systems and battery-operated vehicles such as eBikes and drones.
Isolated base rectifier modules rated up to 3.6kV
IXYS Corporation has announced that its wholly owned UK subsidiary, IXYS UK Westcode, announces an extension to the voltage range of its pressure contact isolated base dual rectifier diode modules. The module is rated up to 3.6kV and available in three diode configurations.
Wall-mount UPS powers for longer
Powersolve's WM Series of uninterruptible power supplies are wall-mount units designed to provide back-up power for long periods. Rated from 800VA/600W to 4000VA/3000W, the WM Series accepts a wide AC input range while providing a pure sine wave output for up to several hours or more.
DC-DC step down converter meets noise sensitive situations
The Enprion EN362Q1 power system on a chip (PowerSoC) DC-DC step-down converter from Altera is now being shipped by distributor Mouser Electronics. The converter is a high-efficiency, integrated synchronous DC-DC step-down buck converter with an integrated inductor, PWM controller, MOSFETs, and compensation.
