  • AN-2034 LM3445 -120VAC, 8W Isolated Flyback LED Driver (Rev. C)
    PDF, 24.5 Mb, Revision: C, File published: May 1, 2013
    This demonstration board highlights the performance of a LM3445 based Flyback LED driver solution that can be used to power a single LED string consisting of 4 to 8 series connected LEDs from an 90 VRMS to 135 VRMS, 60 Hz input power supply. The key performance characteristics under typical operating conditions are summarized in this application report.
  • 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
