Alpha and Omega Semiconductor announced the release of a Fast Switching 600 V αMOS5™ Super Junction MOSFETs in SMD-type TOLL Package. αMOS5 is AOS’s latest generation of high voltage MOSFET, designed to meet the high efficiency and high-density needs...

Fan noise is becoming a significant issue as electronic equipment increasingly enters the office and the home. Noise is proportional to fan speed, and the airflow – hence, fan speed – necessary for cooling is less at low ambient temperatures...

The Optoelectronics group of Vishay Intertechnology introduced two new fully integrated Automotive Grade proximity sensors with high resolution up to 20 µm for force sensing applications...

Voltage supervisors have provided analog voltage monitoring to digital circuits for decades. Texas Instruments released the original TL7705 in 1983; it consumed 1.8 mA, came in a plastic dual-inline package and you can still purchase it today...

Dialog Semiconductor announced the SLG47004, Dialog’s first Advanced Analog GreenPAK™ IC. The SLG47004 integrates an instrumentation amplifier with auto-trimming, digital pots, analog switches and a myriad of digital functions with in-system programmability in a small 3 mm × 3 mm solution size...

P-channel MOSFETs can simplify designs when you use them as high-side switches on circuits with voltages exceeding 100 V dc. When driving a MOSFET, you must rapidly charge and discharge the input capacitance between its gate and its source to reduce heat losses...

Diodes Incorporated announced the PI4ULS3V4857, a SD 3.0-compliant bidirectional level translator for use in communication, consumer, and computing system applications including smartphone handsets, notebooks, SD/MicroSD card readers, wireless access points, and 5G femtocells...

A designer who uses a phototransistor to convert a modulated optical signal to an electrical signal frequently encounters problems when high-intensity background light saturates the phototransistor...

Power Integrations announced the MinE-CAP IC for high power density, universal input AC-DC converters. By halving the size of the high-voltage bulk electrolytic capacitors required in offline power supplies, this new type of IC enables a reduction in adapter size of up to 40%...

A four-quadrant dc-dc converter offers an elegant way to control currents and voltages, and is able to set current to any level...
