Dubbed a DB-THG (drinking-bird triboelectric hydrovoltaic generator), power is extracted from the movement of the bird by the rubbing action of different materials – think rubbing a balloon on a jumper to build up charge. Driven by the cooling effect of water evaporation and the movement of a low boiling point liquid within its glass […]
DGH types work up to 8.1V (-40 to +65°C) and measure between 25 x 8.5 x 16mm high for the 330mF version, to 39 x 13 x 33mm for the 5F. They will also work up to 85°C if max voltage is reduced to 6.9V. Estimated operating life is 1,500 hours at rated temperature and […]
Passive RFID tags have been widely adopted, and some applications show creative adaptation to unmet needs. It’s interesting to see how advances in technology often are adapted to applications that were not highlighted in their original “use case” scenarios and how clever people adapt or leverage new technologies in unscripted ways. A good example of […]
Called LT8418, this IC looks very much like the output stage used within the recently announced GaN driving dc-dc controller ICs LTC7890 and LTC7891. Both high-side and low-side outputs have separate pull-up and pull-down connections on the IC package channels so that additional resistors can be used to tune GaN transistor turn-on and turn-off times […]
The first member of its NeoPower (NP) family of configurable multi-output supplies, it has eight output slots for configuration and 18W/inch3 claimed density for ~283 x 203 x 64mm chassis. Input is single-phase 90 – 132Vac and 180 – 264Vac. “NP08 also has integrated and flexible communication capabilities with optional dongles that support all common […]
Pondering future system-in-package designs that will consume around 1kW, Intel has used a 16nm finfet cmos process to created a prototype 52 phase buck converter that can be built into such ICs, which it revealed at the International Solid-State Circuit Conference in San Francisco. The point-of-load dc-dc takes in 2V and can deliver 200A (624A […]
The flip-side are the disadvantages, warranting a mushrooming component count to temper them. Enter the University of California, San Diego, which, together with France’s CEA-Léti semiconductor lab, decided to build a custom IC to swallow any number of transistors required to beat the problems, and their results were revealed at the International Solid-State Conference in […]
Panasonic has introduced the ZV Series – an Electrolytic Polymer Hybrid capacitor with advanced characteristics. It achieves a maximum Ripple Current (3.3~4.6 Arms) – claimed to be approximately 50% higher than comparable case-sizes. While comparable capacitors usually come up with a ESR of around 16 mΩ at 35V, the ZV series has an ESR of […]
International Solid-State Circuits Conference in San Francisco always seems to make space for audio amplifier developments, and this year is no exception, with some extraordinary distortion and noise figures from Class-D amplifiers, plus a sophisticated Class-H scheme to improve headphone amplifier efficiency. Starting with that headphone amplifier: Class-H is a way to decrease the dissipation […]
