'Fit and forget' miniature battery suits IoT sensors

'Fit and forget' miniature battery suits IoT sensors
A miniaturised solid state battery technology for IoT devices, the Stereax M250 has been introduced by Ilika, a spin-out from the School of Chemistry at the University of Southampton. Addressing the key challenge of always-on, self-charging and efficient energy, Ilika’s Stereax battery family will enable smaller, higher energy-dense batteries to accelerate IoT products to market.

DC/DC converters feature an internal 18V operation driver transistor

DC/DC converters feature an internal 18V operation driver transistor
Torex Semiconductor has launched the XC9263/XC9264 series of synchronous step-down DC/DC converters with an internal 18V-operation driver transistor and an output current of 500mA. A shift from LDO to DC/DC is gaining strength in recent years in order to reduce standby power consumption. Power consumption also is being reduced in digital audio/visual equipment, large household appliances and industrial equipment and the demand for low power consumption by PFM control is increasing.

DC/DC converters features operational life of 30 years

DC/DC converters features operational life of 30 years
The BHT-319R-F4 series of DC/DC converters is designed for an operational life of 30 years at high temperatures in railway and industrial environments. The convection cooled units deliver 300W continuous output power over a -40 to +85°C temperature range without derating. By eliminating optocouplers and electrolytic capacitors, the MTBF of the units is significantly higher than in conventional converter designs.

0.8A step-up DC/DC converters feature load disconnection function

0.8A step-up DC/DC converters feature load disconnection function
Torex Semiconductor has launched the XC9141/XC9142 series of 0.8A step-up DC/DC converters with a load disconnection function. The demand for internal-driver, step-up DC/DC converters in a small package for use in portable devices has been increasing in recent years. There is also an increasing demand for products equipped with an input–output disconnection function (load disconnection function) to prevent malfunctioning during standby, and for device functionality that enables power supply to RTC.

Superfast light source made from artificial atom

Superfast light source made from artificial atom
New research results from the Niels Bohr Institute show that light sources can be made much faster by using a principle that was predicted theoretically in 1954. The results are published in the scientific journal, Physical Review Letters. Researchers at the Niels Bohr Institute are working with quantum dots, which are a kind of artificial atom that can be incorporated into optical chips. In a quantum dot, an electron can be excited (i.e. jump up), for example, by shining a light on it with a laser and the electron leaves a 'hole'.
