High-Linearity Analog Optocouplers

Posted on 01 December 2019

      Extend Working Insulation Voltage to 1.4 kV High linearity analog optocouplers provide the versatility required to meet a wide range of analog isolation needs. For designers of high voltage applications, high linearity analog optocouplers can reliably send analog signals across very high voltage area and low voltage area without distortion. By Chen [...]

Why Constant Current Drives Beat Voltage-Resistor Drives in LED Lighting

Posted on 01 December 2019

       Constant current boost converter improves the energy utilization The design considerations for LED lighting systems powered by 1, 2 or 3-cell battery sources are to say the least numerous: battery energy utilisation, battery life, constant luminous flux output, the light signature (colour temperature), solution size, weight and of course total solution cost. [...]

New Applications for Optical Sensors

Posted on 01 November 2019

       Triangulation sensor instead of camera Infrared sensors that work using the triangulation principle also measure accurately on reflective surfaces and are not affected by either light scatter or high temperatures. When used with a pyroelectric resistor, the wide-angle versions can even distinguish between people and objects. They can therefore be used in [...]

Revolution in the Cockpit

Posted on 01 September 2019

       TFT liquid crystal screens and optoelectronics change passenger compartments. So-called Central Information Displays (CID) continue to appear in more and more car dashboards. Although the CIDS are mainly used in luxury cars at the moment, experts estimate an average growth of around thirteen percent per annum in Europe over the next few [...]

Simple Technique for LED Driver Applications

Posted on 01 April 2019

       Minimizing input supply ripple current LED applications in the consumer market have really taken off like a wild mushroom. In the past they were very popular in cell phone applications, but now you find them in home lighting applications, airplane cabin lights, automotive headlights, MP3 players, etc. By Ajmal Godil, Intersil   [...]

Specifying Optocouplers for Safe and Robust Industrial Systems

Posted on 01 March 2019

      Isolators for IEC/EN/DIN EN 62019-5-2 In the industrial field the system level safety standards are IEC (International Electrotechnical Commission) 6041 for worldwide or international standards, UL5082 (from Underwriters Laboratories) for the United States and EN 501783 (from the European Union) for Europe. At the component level for optocouplers, the safety standards are [...]
