Anwendungshinweise

  • An Improved Line Regulation Solution Used in LM3444/5 Non-Isolated LED Lighting
    PDF, 1.0 Mb, Datei veröffentlicht: Oct 25, 2012
  • AN-2097 LM3444 - 230VAC, 8W Isolated Flyback LED Driver (Rev. F)
    PDF, 5.4 Mb, Revision: F, Datei veröffentlicht: May 1, 2013
    This is a four-layer board using the bottom and top layer for component placement. The demonstration board can be modified to adjust the LED forward current, the number of series connected LEDs that are driven and the switching frequency.
  • AN-2082 LM3444 -120VAC, 8W Isolated Flyback LED Driver (Rev. E)
    PDF, 6.4 Mb, Revision: E, Datei veröffentlicht: May 1, 2013
    This demonstration board highlights the performance of a LM3444 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 note.
  • 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
