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 - Driving LEDs: To Cap or Not to CapPDF, 542 Kb, Archivo publicado: marzo 21, 2007
- AN-1656 Design Challenges of Switching LED Drivers (Rev. A)PDF, 171 Kb, Revisión: A, Archivo publicado: mayo 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
