  • The Future of Farming: Philips’ Horticulture LEDs

    Posted Apr 23, 2014 By EEWeb
    A warehouse aglow with LEDs may well sound like a vision of the future, but for Philips Lighting, it exemplifies the future of farming. In the face of a surging world population and dwindling natural resources, indoor farming is increasingly playing a bigger role in feeding urban populations. While energy demands have been consistent barriers to this burgeoning industry, the rise of new...
  • Combining Capacitive Sensing and LED Lighting - Part 1

    Posted Apr 23, 2014 By EEWeb
    Capacitive touch sensing is the very popular technology used to implement intuitive user interfaces in many electronics applications including smart phones, tablets, LCD/LED TVs, and many others. Touch buttons are fast replacing traditional mechanical buttons. However, unlike mechanical buttons which provide tactile feedback to users by their nature, touch buttons need additional components to...
  • Structured Design of Switching Power Transformers

    Posted Apr 22, 2014 By Coilcraft
    Design of switching power transformers can be accomplished in a relatively simple manner by limiting magnetic configurations to a few core and coilform structures. These structures have been chosen both for their versatility and their low cost. Dimensional information as well as design information in the form of design curves for the chosen structures may be found at the end of this document. By...
  • What is the Lifespan of a Solar Panel?

    Posted Apr 22, 2014 By Tom Lombardo

    Photovoltaic (PV) modules typically come with 20 year warranties that guarantee that the panels will produce at least 80% of the rated power after 20 years of use. The general rule of thumb is that panels will degrade by about 1% each year. Is that rule accurate?

    Degradation Rates

    The National Renewable Energy Laboratory (NREL) performed a meta-analysis of studies that examined…

  • Leadless Slim Package Minimize System Size

    Posted Apr 22, 2014 By Fairchild Semiconductor
    Delivering the energy to each server and telecom systems uses power and generates heat, which requires additional energy in cooling system. Every watt consumed by servers and telecom equipments generally wastes at least another watt through cooling, power backup, and power delivery. Therefore, a major effort in modern data and telecommunication power systems has been increasing the efficiency and...
  • 15 W on Buck Boost Reference Design

    Posted Apr 22, 2014 By Melexis
    The scope of this application note is to show EMC measurement results of a 15 W implementation using 6 white LEDs at 700 mA on the Buck Boost reference design board EVB10803_5.
  • Normally-off and Current Collapse Free GaN Transistor

    Posted Apr 22, 2014 By Mouser
    Current trends of power supply design, both for industrial and commercial applications focus on higher efficiency and increased power density that are beyond the capability of MOS technology. This leads design engineers to look for MOS alternative devices that will be able to cater the needs of the modern power supply and power management systems. This is the start of the conception of Gallium...
  • Timekeeping Accuracy with RTCs using External Temp Sensor

    Posted Apr 21, 2014 By NXP
    The temperature dependent characteristics of quartz crystals prevent time keeping also with state-of-the-art real time clocks from being highly accurate over a wide temperature range, unless corrective measures are implemented. This application note describes how the use of an external temperature sensor, placed in a location which will be at or near the same temperature as the quartz...
