The long road towards emissive QLEDs
IDTechEx Research have reviewed the potential evolution roadmap of material technologies in emissive displays. First, fluorescent OLED materials were developed. These offered narrow emission, maturity, and stability, but suffered from low internal quantum efficiency (IQE) due to their inability to harvest the so-called triplet states.
LED drivers for advanced vehicle lighting applications
ON Semiconductor has launched a new family of four devices that facilitate the high levels of performance and innovative functionality that vehicle manufacturers and consumers now expect from automotive exterior and interior lighting. Aimed specifically at low power solid state lighting, the new family comprises two LED drivers (NCV7683 and NCV7685) and two current controllers (NCV7691 and NCV7692).
DC-DC converters withstand high test voltages
High-voltage regulated DC-DC converters aimed primarily at electronic engineers designing IT equipment for industrial, instrumentation and transportation applications are available at RS Components. The TRI Series power converters from TRACO Power combine a sophisticated reinforced isolation system, able to withstand high test voltages, with high common-mode transient immunity.
Single-chip industrial radar sensor integrating a radar accelerator
The IWR1843 device from Texas Instruments is an integrated single-chip mmWave sensor based on FMCW radar technology capable of operating in the 76 to 81GHz band with up to 4-GHz continuous chirp. The device is built with the low-power 45nm RFCMOS process from Texas Instruments. This solution enables high levels of integration in an extremely small form factor.
MOSFET offers on-resistance times gate charge
Vishay Intertechnology has introduced a new 80V TrenchFET Gen IV n-channel power MOSFET in the 6.15 by 5.15mm PowerPAK SO-8 single package. Designed to save energy by increasing the efficiency of power conversion topologies and switching circuitry, the Vishay Siliconix SiR680ADP offers on-resistance times gate charge, a key figure of merit (FOM) for MOSFETs used in power conversion applications of 129 mΩ*nC.
80V MOSFET on-resistance times increase efficiency
An 80 V TrenchFET Gen IV n-channel power MOSFET in the 6.15mm by 5.15mm PowerPAK SO-8 single package has been introduced by Vishay Intetechnology. Designed to save energy by increasing the efficiency of power conversion topologies and switching circuitry, the Vishay Siliconix SiR680ADP offers on-resistance times gate charge — a key figure of merit (FOM) for MOSFETs used in power conversion applications — of 129 mΩ*nC.
Demand for EVs will influence power electronics
Increase in carbon emission levels is driving the adoption of sustainable sources of energy such as solar, wind and geothermal over conventional forms. In 2017, emissions from electricity accounted for 28% of the total GHG emissions in the US. Efforts to implement sustainable power generation systems will bring in remarkable opportunities for power electronics industry players.
