IC increases software power-measurement accuracy
The immediate availability of a precision power- and energy-monitoring chip has just been announced by Microchip. The PAC1934 works in conjunction with a Microchip software driver that is fully compatible with the Energy Estimation Engine (E3) built into the Windows 10 operating system to provide 99% accuracy on all battery-powered Windows 10 devices.
DC/DC converter designed for railway and transportation
TRACO POWER has announced the release of their THN 15WIR family of ruggedised DC/DC converters designed for harsh environments in a miniature 1x1x0.40” footprint. The converters offer increased resistance against electromagnetic interference, shock/vibration and thermal shock with EN 50155 and EN 61373 compliance making them suitable for railway, transportation and harsh industrial environments.
Power saving needed to meet bandwidth demands
Tony Lefebvre, VP of Product Management and Marketing at optical transceiver specialist, ProLabs, here addressed why monitoring power consumption is integral to manage data centre environments.
DC/DC buck converter features innovative control topology
Texas Instruments has introduced the 16V input, 40A synchronous DC/DC buck converter with an internally compensated Advanced-Current-Mode (ACM) control topology supporting frequency synchronisation. TI’s TPS543C20 SWIFT converter provides enhanced efficiency by integrating its latest generation of low resistance high and low side MOSFETs into a thermally efficient small-footprint package.
A 94% efficient offline flyback switcher IC
Power Integrations has announced the release of its InnoSwitch3 family of offline CV/CC flyback switcher ICs. The new devices achieve up to 94% efficiency across line and load conditions, slashing power supply losses by a further 25% and enabling the development of compact power supplies up to 65W without heatsinks.
RF transistor's 65V LDMOS technology speeds power design
Availability and full design support capabilities for a new 65V, wideband RF power LDMOS transistor from NXP Semiconductors has been announced by Richardson RFPD. The MRFX1K80H is the first product in NXP's MRFX series. It is designed to deliver 1800W CW at 65V for applications from 1.8 to 400MHz and is capable of handling 65:1 VSWR.
Can electrical installations cope with smart home demands?
In the last two decades electronic devices have seen a fundamental change, and so has user behaviour. Now people have more devices than ever before and they often run off the same circuit. From standard home appliances, laptops, gaming consoles, to lighting, the load on household cables is becoming increasingly higher. Thomas Kruse, Product Manager at reichelt tells us more...
Let's go back to basics with choosing the perfect regulator
Two main functions are provided in voltage regulators: changing the input voltage to a different level at the output and regulation (maintaining a constant output voltage despite changing load conditions). DC/DC Regulators are a key component in any power system, and so choosing the correct regulator is critical if an optimum solution is to be developed.
Higher performance in artificial intelligence applications
Big demanding applications such as artificial intelligence, machine learning and bog data mining are driving CPU/GPU/ASIC (‘XPU’) processor operating currents to hundreds of Amperes. As these currents increase, the remaining short distance to the XPU, the ‘last inch’ in point-of-load power architectures, have become a limiting factor in XPU performance and total system efficiency.
Stepping motor driver IC with anti-stall feedback architecture
Toshiba Electronics Europe (TEE) has announced the launch of a stepping motor driver (TB67S289FTG) with a Toshiba-developed architecture that automatically detects and prevents stalling during operation. Stable and highly precise control is a basic operating requirement for motors used in printers, office appliances, banking terminals (including ATMs), cash dispensers and home appliances. Recent requirements have also emphasised more efficient mo...
