  • Power Seminars Focus on Engineering Energy Efficiency

    Posted Apr 24, 2014 By Fairchild Semiconductor
    If you’re looking for the latest and greatest technical information on new, advanced power supply concepts, then you need to be at Fairchild’s Power Seminar series as it swings through North America and Asia in May and June. One of the main topics is Current Shaping Strategies for Buck Power Factor Correction. In this session, two possible control techniques for a buck PFC converter are...
  • Message Encryption using SHA Devices

    Posted Apr 23, 2014 By Maxim
    This document shows how Maxim's DS1963S SHA iButton® can be used with small microcontrollers to provide strong encryption and authentication of control and status messages, telemetry, or sensitive process control information. For low cost and low overhead, it provides nonvolatile memory, secure secret storage, secret sharing and rotation, fast SHA-1 pad generation, and a globally unique serial...
  • 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.
