60V Dual DC/DC controller features I²C-based PMBus interface
Linear has announced the LTC3886, a 60V input dual output synchronous step-down DC/DC controller with programmable loop compensation and I²C-based PMBus interface. This controller employs a constant-frequency, current-mode architecture with programmable output voltage up to 13.8V. The LTC3886 suits harsh environments requiring a high input voltage range, such as in factory automation, industrial, medical, communications and avionic appl...
Material gains produce cost competitive inductors
With its new inductor series UHEI and HPPC, Chilisin is targeting applications in automotive electronics. The inductors are available at distributor Rutronik as of now. Using its powder-making plant Chilisin is able to provide inductors that combine reliability and competitive cost structure.
The era of practical fusion power may be approaching
It’s an old joke that many fusion scientists have grown tired of hearing: Practical nuclear fusion power plants are just 30 years away - and always will be. But now, finally, the joke may no longer be true: Advances in magnet technology have enabled researchers at MIT to propose a new design for a practical compact tokamak fusion reactor - and it’s one that might be realized in as little as a decade, they say.
Compact 5W wall plug adapters meet DOE Level VI standard
CUI has announced a line of ultra-compact 5W wall plug adapters for the US, Japanese and European markets featuring an integrated USB connector. The SWI5-5-N-I38 and SWI5-5-E-I38 are designed to meet the stringent average efficiency and no load power requirements mandated by the US Department of Energy (DOE) set to go into effect on February 10, 2016.
A better way to study Li-air batteries
If Li-air batteries live up to their promise, we could one day be driving electric cars 500 miles or more without recharging, or using laptops for weeks without having to plug in. They could also replace Li-ion batteries, currently the standard in many consumer electronics.
Power inductor offers high current characteristics
The SMD power inductor range at Dengrove Electronic Components has been strengthened by the addition of Taiyo Yuden’s MDWK4040. Part of the company’s MCOIL MD series, this new size inductor measures 4.0 x 4.0 x 2.0mm (maximum height) and can be used as choke coils for power supply circuits in increasingly sophisticated information technology equipment, for example.
'Yolks' & 'shells' improve rechargeable batteries
One big problem faced by electrodes in rechargeable batteries, as they go through repeated cycles of charging and discharging, is that they must expand and shrink during each cycle, sometimes doubling in volume, and then shrinking back. This can lead to repeated shedding and reformation of its ‘skin’ layer that consumes lithium irreversibly, degrading the battery’s performance over time.
Low voltage input converter suits military vehicles
Stadium Power has added a new low profile, non-isolated, low voltage input converter for use on military and non-tactical vehicles to their range of military COTS power products. The low voltage input capability prevents the converter from turning off when the vehicle’s engine is cranking, ensuring continuous operation of electronic equipment connected to its output.
Hyper-fast rectifier is suited for PFC applications
Designed specifically for use as a boost diode for PFC and continuous conduction mode applications, the DSR8F600 has been introduced by Diodes Incorporated. The 600V, 8A rectifier features a hyper-fast 20ns reverse-recovery time which reduces PFC MOSFET switching losses, increases switching speed and improves energy efficiency.
Automotive buck regulator ICs target USB charging
Extending its portfolio of automotive regulator ICs, Allegro MicroSystems Europe has introduced two high output current devices suiting USB power applications. The A8652 and A8653 synchronous buck regulator ICs provide tight load regulation over a wiring harness without the need for remote sense lines.
