  AN-1656 Design Challenges of Switching LED Drivers (Rev. A)
  PDF, 171 Кб, Версия: A, Файл опубликован: 3 май 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
