E-trucks with overhead power lines to be tested on Autobahn
E-trucks with overhead power lines to be tested on Autobahn
02.03.2017 · News
The idea of overhead power lines for electric vehicles is not new – after all, in the railway industry it is rather common. For electric trucks, it also has been considered for a while. Now the German government plans to test the technology on public highways...
Cap-Drop Approach Implements Offline Power Supply for Light Loads
"Cap-Drop" Approach Implements Offline Power Supply for Light Loads
01.03.2017 · Circuits
Low-power applications such as e-meters (electricity or energy meters) often require a simple ac line-powered supply where a 3.3-V rail powers a microcontroller and charges a lithium-ion battery to 4.2 V. You can implement this with a mains-frequency power transformer or with a more complicated ac-dc (offline) power supply...

Diodes Incorporated introduced the AP3984 high-performance power switcher. With its unique integrated high-voltage start-up circuit, this device provides a cutting-edge solution for line-powered chargers and adaptors in the consumer and industrial markets...
Choosing a Precision Op Amp? Trust Goldilocks
Choosing a Precision Op Amp? Trust Goldilocks
28.02.2017 · Articles
Choosing the appropriate bandwidth for an application of a precision op amp is a lot like the experience of Goldilocks trying to choose between the three bears’ bowls of porridge – one bowl was too hot, one bowl was too cold, and one was just right...
Intersil Announces Industry's Smallest Isolated RS-485 Transceiver
Intersil Announces Industry's Smallest Isolated RS-485 Transceiver
28.02.2017 · News
Intersil Corporation announced the industry's smallest isolated RS-485 differential bus transceiver designed to provide 4 Mbps bidirectional data transmission for Industrial Internet of Things networks. The high-speed ISL32704E delivers industry-leading electromagnetic interference and common-mode transient immunity in a small 4 mm × 5 mm QSOP package that is 70% smaller than competitive devices...

27.02.2017 · News
Allegro MicroSystems, LLC introduces a new programmable linear Hall-effect sensor IC designed for applications that require high accuracy and high resolution without compromising bandwidth. Allegro’s A1377 employs segmented, linearly interpolated temperature compensation technology...
How to measure capacity versus bias voltage on MLCCs
How to measure capacity versus bias voltage on MLCCs
26.02.2017 · Circuits
High-capacity, multilayer ceramic capacitors have a property often not well understood by electronic designers: the capacitance of these devices varies with applied DC voltage. This phenomenon is present in all high-dielectric constant, or Class II capacitors. However, the amount of variation can differ considerably among different MLCC types...
Crystal orientation a breakthrough for solar tech
Crystal orientation a breakthrough for solar tech
26.02.2017 · Articles
Researchers from Los Alamos National Laboratory, Northwestern University and Rice University have tweaked their crystal production method and developed a type of two-dimensional layered perovskite with outstanding stability and more than triple the material’s previous power conversion efficiency, in a step that could bring perovskite crystals closer to use in the burgeoning solar power industry...
