UnitedSiC has launched a simple on-line design tool to calculate power losses and other parameters for power supplies using the company’s silicon carbide transistors and diodes. Called FET-Jet Calculator, no registration is needed, although you do have to click a minimal user agreement. This is not the sort of tool that tells you which transistors ...

Smart Bench Essentials is a group of four stackable lab bench instruments from Keysight that are coupled through a single graphical interface for integrated data management and analysis, and remote operation. “All four instruments have a consistent look and feel, the same graphical user interface and connectivity,” said company v-p Christopher Cain. They all have ...

Vishay has announced power stages for synchronous buck converters that allow a logic-level PWM signal to control 70, 80 or 100A outputs. There are six parts that will handle inputs from 4.5 – 16V (see table below) then four that will handle 4.5 – 21V – there is no 100A option in the higher voltage devices. ...

Nichia is claiming better colour rendering without loosing efficacy with technology it has banded ‘H6’. “Indeed, the H6 series delivers a colour rendering index of 90 while maintaining a level of efficacy seen in standard CRI 80 leds,” it claimed. It takes advantage of a red narrow band phosphor, as well as semiconductor and package changes, to ...

Toshiba is aiming at high ripple rejection in a family of CMOS linear voltage regulators in a ~0.7 x 0.7mm WCSP4F package. Called the TCR5RG series, the low drop-out parts cover an output voltage range of 900mV to 5V. Achieved through the combination of a wide-gap internal circuit topology, an integrated high-speed operational amplifier and ...

Panasonic has produced a 6pin DIP-style opto-relay that can switch 1.2kV at 750mA. Called AQV209G, it comes in through-hole and surface-mount versions and has a single ac-dc output with two mosfets that can be wired back-to-back series to switch ac (‘A’ connection), or in parallel to switch dc at higher current (‘C’ connection). In this ...

Russian scientists working with high-pressure room-temperature superconductors have had an anomalous result that hints at another mechanism for the effect beyond established models. Leading an international team, Artem Oganov (Skoltech and MISIS) and Ivan Troyan (Russian Academy of Sciences) performed theoretical and experimental research on the high-temperature superconductor yttrium hydride (YH6). Over the last few ...
