Industry's highest current 40A, 16VIN converter
Texas Instruments has introduced the industry's first 40A, 16VIN synchronous step-down DC/DC converter with true differential remote-voltage sensing. The SWIFT TPS548D22 buck converter features a small PowerStack package and integrated MOSFETs to drive ASICs and DSPs in space-constrained applications.
Thermal bag to counter fire risk from Li-ion batteries
Morgan Advanced Materials has introduced to the aviation market a novel means of tackling the risk posed by overheating lithium-ion batteries, following an extensive period of testing in conjunction with Germanwings, part of the Lufthansa Group. The FireMaster battery bag, which measures 500x500mm, comprises two of Morgan’s specialist thermal materials to create a sealable, water-resistant compartment capable of containing the heat spread i...
Magna-Power releases 66 programmable DC power supply models
Magna-Power Electronics added 66 new models to its already expansive line-up of programmable DC power supplies. The 25, 60 and 300VDC models are offered at every power level for the company’s DC power supplies, across 5 product lines from 1.5kW to 1000 kW+. The 66 new models are available immediately at standard pricing and lead-time.
Better combustion for power generation
In 2015, the search for efficiency gains led GE to tackle one of the most complex problems in science and engineering—instabilities in gas turbine combustors. The journey led the company to the Titan supercomputer at the Oak Ridge Leadership Computing Facility (OLCF), a US Department of Energy (DOE) Office of Science User Facility located at DOE's Oak Ridge National Laboratory.
Fuel gauge eliminates the need for battery characterisation
Easing and securing the implementation of pack-side battery gauges in portable devices, the ModelGauge m5 portfolio has been announced by Maxim Integrated Products. The MAX17201/MAX17205 and MAX17211/MAX17215 fuel gauges are claimed by the manufacturer to be the industry’s first to integrate SHA-256 for secure authentication to prevent battery clones.
Rays provide power for an electric generator
Scientists from the RIKEN Quantitative Biology Center in Japan removed the electric organ from a torpedo and chemically stimulated the organ by injecting a solution of the neurotransmitter acetylcholine though a syringe. They were able to achieve more than a minute of continuous current, with a peak voltage of 91 mV and 0.25 mA of current. By increasing the number of syringes, they achieved a peak voltage of 1.5 V and a current of 0.64mA.
Keeping a step ahead with Vincotech's three level design
Vincotech has announced the launch of a unique three-level solution for high-voltage solar and ESS applications. The cost-efficient new flowNPC 1 split meets the demands of sophisticated devices by combining two fast modules to improve thermal performance and enable four-quadrant operation.
Unipolar Hall-effect switch features built in diagnostics
Featuring an externally enabled diagnostic function and user-programmable switchpoints, Allegro MicroSystems Europe has announced a unipolar Hall-effect switch. The A1162 has on-chip electromagnetic coils that are used to implement self-test of the sensor’s entire magnetic and electrical signal chain. It is designed for systems where precise magnet switchpoints and safety, reliability or both, are critical, such as those designed to meet th...
