High-current, pulsed-laser diode driver board targets lidar designs
Efficient Power Conversion (EPC) announces the availability of the EPC9150, a 200 V, high current, pulsed-laser diode driver demonstration board. In a lidar system, used to create 3-D maps for autonomous vehicle applications, speed, and accuracy of object detection are critical. As demonstrated by this board, the rapid transition capability of the EPC2034C eGaN FETs […]
Hybrid lithium-ion supercaps deliver up to 220 F at 3.8 V
Cornell Dubilier Electronics introduces two new series of Hybrid LIC Supercapacitors in response to the growing need for ultra-high capacitance values at higher operating voltages. The new VMF and VPF Series operate at 3.8 WVDC with capacitance values up to 220 Farads. The higher voltage results in increased energy density. With nearly eight times the energy density and a […]
Side-emitting infrared LED targets head-mounted displays, industrial headsets, VR/MR/AR apps
ROHM introduced the new CSL1501RW ultra-compact side-emitting (side view) infrared LED. The device is ideal for head-mounted displays, industrial headsets, and VR/MR/AR (xR, virtual reality) gaming systems. In recent years, VR/MR/AR technology, which has emerged following the continuing advancement of IoT, is being increasingly adopted in headsets and head-mounted displays in a variety of gaming systems.

Vishay Intertechnology, Inc. today introduced a new AEC-Q101 qualified p-channel -100 V TrenchFETMOSFET designed to increase power density and efficiency in automotive applications. Not only is the Vishay Siliconix SQJ211ELP the industry’s first such device in the compact 5 mm by 6 mm PowerPAK SO-8L package with gullwing leads, but it also features best in […]
Single IC integrates power, voltage, and current monitoring, reinforced isolation
Allegro MicroSystems announced the launch of the ACS37800, a Hall-effect power monitoring IC for single-phase AC and DC solutions in a small PCB footprint. Another industry-first innovation, Allegro’s ACS37800 is an integrated power monitoring chip that allows simultaneous measurement of power, voltage, and current for AC and DC signals with an isolation rating of up […]
Power-management ICs optimized for use in laptops
MagnaChip Semiconductor Corporation announced a new line of power management integrated circuits (PMIC) by introducing its first UHD display panel PMIC for laptops. PMICs are integrated circuits that include multiple power management functions within a single chip, and they are frequently used to power space-constrained devices where high-efficient and compact form factors are required. They […]
Project: Implementing a 4xN LED driver
by Dialog Semiconductor LED displays are widely used in systems ranging from digital clocks, counters, timers, electronic meters, basic calculators, and other electronic devices capable of displaying numerical information. Figure 1 depicts an example of a 7-segment LED display which can show decimal numbers and characters. As each segment on the LED display can be […]
Want to kill Covid? 30 sec under 285-nm UV-LEDs will do it
Researchers from Tel Aviv University found that UV light at a wavelength of 285 nm was almost as efficient in disinfecting the Covid virus as a wavelength of 265 nm, requiring less than half a minute to destroy more than 99.9% of the coronaviruses. They say this result is significant because the cost of 285-nm […]
