Step-down silent switcher 2 delivers 94% efficiency at 2MHz
Analog Devices, which recently acquired Linear Technology, has announced the LT8645S, an 8A, 65V input capable synchronous step-down switching regulator. Its Silent Switcher 2 architecture uses two internal input capacitors as well as internal BST and INTVCC capacitors to minimise the area of the hot loops. Combined with controlled switching edges and internal construction with an integral ground plane and the use of copper pillars in lieu of bon...
ROHM showcases expanded range of power devices at PCIM 2017
ROHM Semiconductor will debut its latest power product designs at PCIM, the leading trade fair for Power Electronics, Intelligent Motion and Energy Management in Nuremberg, from May 16 – 18, 2017 (Hall 9, Booth 316). Energy savings and reduced system costs in all kinds of systems are heavily influenced by choosing the right power device.
Rogowski AC current probes measure next-gen semiconductors
Power Electronic Measurements (PEM) will showcase its full range of Rogowski based CWT and RCT AC current probes at PCIM Europe 2017. Visit the company at PCIM Europe 2017 (Hall 7-122) for live demonstration of the CWT MiniHF probe.
Boost, flyback & SEPIC controller operates up to 175°C
Analog Devices, which recently acquired Linear, announces the LTC1871X, a wide input range, current mode, boost, flyback or SEPIC controller that drives an N-channel power MOSFET and requires few external components. Intended for low to medium power applications, it eliminates the need for a current sense resistor by utilizing the power MOSFET’s on-resistance, thereby maximizing efficiency. The LTC1871X’s design is optimized...
How to manage power in electronic systems
Semiconductors manage power in electronic devices by converting, distributing, storing, discharging, isolating and measuring electrical energy.
ECP technology enables evaluation of converter on GaN basis
Fraunhofer IAF has developed a fully integrated monolithic multilevel converter in high-volt AlGaN/GaN-on-Si technology. The integrated inverter circuit is designed for maximum voltages of +/- 400 V and currents of 5 A. The multilevel converter on an area of just 2 × 3 mm² comprises four transistors and six diodes. It provides a perfect solution for compact voltage converter applications. It was possible to demonstrate DC/AC inverter o...
GaN solutions alter the data centre power equation
The age of the hyper-scale data centre is upon us, evidenced by massive data storage farms and the tens of thousands of cloud servers housed in hangar-sized buildings operated by companies like Google, Facebook, Microsoft, and Amazon.

Advanced batteries for long-range electric cars
Limitation in energy density of batteries means in practice reduced driving range for electric cars, which is the largest obstacle to these vehicles entering the market. But, new technology using the reaction of metal and air could have a major impact on battery life. The EU-funded project NECOBAUT (New concept of metal-air battery for automotive application based on advanced nanomaterials) was launched with the aim to incorporate nanomaterials i...
IGBT gate drivers reduce discrete components count
SCALE-2 IGBT gate drivers from Power Integrations are in stock at Mouser Electronics. These flexible insulated gate bipolar transistor (IGBT) gate driver cores integrate commonly required driver functions — including galvanic isolation, protection, and DC/DC conversion — in a single module.
