Build high energy density power supplies with integrated eGaN
High energy density switch-mode power supplies (SMPSs) can accelerate battery charging, reduce the size of solar micro-inverters, and meet the demand of server farm power requirements, all without generating excessive heat. However, engineers are now reaching the performance limits of the silicon MOSFETs and IGBTs that form the primary switching elements of conventional SMPSs. Instead, transistors constructed from enhancement-mode gallium nitride...
How to use a voltage reference for an accurate data conversion
In the rush to more quickly and efficiently connect the analogue and digital worlds to take advantage of the Internet of Things (IoT), it’s easy but unwise to overlook the critical role of the voltage reference. Used by analogue-to-digital (ADC) and digital-to-analog (DAC) converters as the primary standard by which to “judge” the analogue input and output values, it helps ensure accurate signal and data conversion, but only if ...
Flash LED drivers deliver stability in quad-channel applications
Diodes Incorporated has announced the AL3644, a high-speed, dual-channel flash LED driver designed to support advanced camera flash and torch functionality, as offered by the latest smartphones and other portable consumer devices.
New device family reduces standby power for appliance applications
Power Integrations hasannouncedCAPZero-3, the latest generation of the energy-saving X-capacitor discharge ICs. Two-terminal CAPZero-3 ICs enable designers to easily meet IEC60335 safety approvals for major appliances, and cover allcapacitor values from 100-6µF. TheIEC60335 is the discharge safety standard for all appliances. To protect the user from an electrical hazard, it requires the voltage across the input X capacitor to discharge to ...
What are isolated digital inputs?
Digital isolators serve the basic (or often reinforced!) function of providing galvanic isolation digital signal paths. TI isolation structures are capacitive, with the insulation barrier consisting of two high-voltage capacitors built from our complementary metal-oxide semiconductor (CMOS) process technology.
Battery management IC maximises driving range for EVs
Renesas Electronics hasannounced its fourth-generation lithium-ion (Li-ion) battery management IC that offers unmatched life time accuracy. The ISL78714 provides accurate cell voltage and temperature monitoring, along with cell balancing and extensive system diagnostics to protect 14-cell Li-ion battery packs while maximising driving time and range for hybrid and electric vehicles (HEV/MHEV/PHEV/BEV).
Extended ratings open up capacitor applications
Extended Wet Tantalum Capacitors recently optimised by Vishay Sprague Capacitors have been introduced at distributor New Yorker Electronics. The extended ratings means the devices meet industrial, AMS and refinery applications.
High reliability 80W DC/DC converter for demanding applications
Cosel has announced the release of a very high reliability 80W DC/DC converter, the MGF80. Packaged in an industry standard two by one inch, six sided, shielded metallic case, the MGF80 series has been designed to Cosel’s strict criteria for high performance and reliability, contributing to the company’s world class quality with a failure rate of below 30 parts-per-million (ppm).
Laser Components wins ‘Best of Sensors’ 2019 Award
LASER COMPONENTS has been named a ‘Best of Sensors’ 2019 Award winner in the Automotive/Autonomous category. The company’s QuickSwitch Pulsed Laser Diode (PLD) was recognised as one of the Innovative Products of the Year 2019 which highlights advancements and achievements that are moving the sensors industry forward.
Low profile tantalum capacitor for embedded electronics
AVX Corporation has extended its TACmicrochip Series with what is reportedly the lowest-profile 3216-footprint tantalum capacitor currently available on the market. Measuring just 0.5mm high, the first new ‘I’ case capacitor (EIA Metric 3216-05) is rated for 10μF and 6.3V, but will be followed by future code releases to further extend the offering.
