  AN-1982 Small, Wide Input Voltage Range LM2842 Keeps LEDs Cool (Rev. A)
  PDF, 60 Kb, Revision: A, Datei veröffentlicht: Apr 23, 2013
  The world seems to be poised to make the leap to LED lighting. Incandescent has been deemed tooinefficient, which it is, and fluorescent lighting often does not achieve the lifetime it claims. Fluorescentalso has another set of baggage, dangerous chemicals. So the logical choice that most people believe cantake the crown is high brightness (HB) LEDs. HBLEDs are becoming more attractive as th

  AN-1656 Design Challenges of Switching LED Drivers (Rev. A)
  PDF, 171 Kb, Revision: A, Datei veröffentlicht: May 3, 2013
  Using a switching regulator as an LED driver requires the designer to convert a voltage regulator into acurrent regulator. Beyond the challenge of changing the feedback system to control current, the LEDsthemselves present a load characteristic that is much different than the digital devices and other loads thatrequire constant voltage. The LED WEBENCHВ® online design environment predicts and

  Powering & Dimming High-Brightness LEDs w/ LM3405 Constant-Current Buck Reg (Rev. A)
  PDF, 158 Kb, Revision: A, Datei veröffentlicht: May 1, 2013
  This application report describes a few of the many application solutions for the Texas InstrumentsLM3405 LED driver. The LM3405 device is offered in a 6-pin Thin-SOT (SOT) package and operates at aninternal switching frequency of 1.6 MHz, allowing the use of small-value inductors, thereby saving boardspace.
