Proof-of-concept platform evaluates ambient light and heat micro-power sources
Trameto has introduced a proof-of-concept platform for evaluating how to generate a reliable micro-power source from ambient light and heat. Called Severn, the compact platform can be used as a prototype because its size and form factor could be adopted for production. An engineering sample of the TM2040, a four-input, smart EH PMIC is at […]
The humble neon lamp: down, but definitely not out, Part 3
Despite the convenience and availability of LEDs, the neon lamp still has a viable position as a power-on indicator as well as use in some specialty applications. Thus far, we have looked basic neon lamp principles and operation. This part looks at some special issues related to these versatile indicators. Q: Why use a neon […]
The humble neon lamp: down, but definitely not out: Part 1
Despite the convenience and availability of LEDs, the neon lamp still has a viable position as a power-on indicator as well as use in some specialty applications. The classic neon indicator lamp with its reddish-orange glow has been used since the early 1890s. Now, the availability, convenience, longevity, and other attributes of LED-based indicators have […]
Dual-channel DC-DC controllers drive LED automotive headlamps
Infineon Technologies AG expands the LITIX Power family with the dual-channel, stand-alone DC-DC controller TLD6098-2ES. The controller is the first product that can drive a full LED headlamp by itself without an additional microcontroller. It can also operate the four standard LED front light functions: High Beam (HB), Low Beam (LB), Daytime Running Lights (DRL), […]

Surface-mount TVS devices protects circuits in industrial apps
Protek has introduced a series of high-powered surface mount transient voltage suppression components that provide circuit protection in numerous industrial applications. These applications include relay drives, motor start-and-stop electromagnetic field protection, module lightning protection, and secondary lightning protection in AC/DC applications. The SM30KWExxA/CA series consists of many TVS components ranging in rated stand-off voltages from […]
UV-C LEDs kill viruses and bacteria for disinfection systems
Würth Elektronik offers UV LEDs with emission wavelength of 275nm. This wavelength kills germs, by destroying the RNA structure of Viruses and Bacteria. Therefore, those types of LEDs are suitable for disinfection in areas where chemical components are not suitable to use. These can be devices for germicide cleaning of different surfaces, or also for […]
Programmable 3-kW ac-dc supplies reach 400 Vdc
Introducing the HDL3000-HV series of single-phase input 3kW AC-DC power supplies with output voltages from 150V to 400VDC, with up to 800VDC realized by connecting units in series. All models feature output voltage and current adjustment ranging from 0 to 105% using analog (via voltage or resistance) or digital (I2C, RS485, and RS232) interfaces enabling the […]
SMD aluminum chip capacitors deliver high-CV, low-ESR performance
AVX Corporation has released a full range of aluminum capacitors spanning three different electrolytic technologies and six different series. This new range of surface-mount aluminum chip capacitors adds a ninth capacitor type to AVX’s already-extensive capacitor product portfolio, which also includes broadband, ceramic, niobium oxide, polymer, film, RF/microwave, tantalum, and supercapacitor technologies. As such, these six […]
