Application Notes
- AN-2192 LM3492 12VAC, 7W LED Driver for AR111 Application (Rev. A)PDF, 627 Kb, Revision: A, File published: May 1, 2013
The LM3492 demonstration board included in this package is designed for converting nominal 12VACfrom electronic transformer output to drive seven series connected LEDs at 360mA average current. Theend user can directly light up a LED string through the demonstration board from an electronic transformerto test out the performance. With the demonstration board, the LED string not only runs at - AN-1656 Design Challenges of Switching LED Drivers (Rev. A)PDF, 171 Kb, Revision: A, File published: 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
