  • Increasing Full-Load Efficiency of a Backlight Driver
    PDF, 1.2 Mb, 档案已发布: Jun 5, 2013
    This application report discusses a way to increase the efficiency of the boost converter in a backlightdriver by reducing conduction and AC losses in the inductor, thereby increasing the overall efficiency ofthe backlight driver at higher loads.
  • Inductor Selection in Boost Converters for LCD Backlight Applications
    PDF, 764 Kb, 档案已发布: Oct 24, 2016
    White LED drivers for LCD back-light applications are often designed for battery-powered devices. This makes circuit size and efficiency crucial. Because of this, selecting the optimal inductor is one of the mostimportant aspects of the design. This application note discusses the important parameters of the inductorand how to select the right inductor for the application.
  • Schottky Diode Selection in Asynchronous Boost Converters
    PDF, 491 Kb, 档案已发布: Sep 6, 2016
    Asynchronous boost converters require a Schottky diode as the rectifying element due to the diode's lowforward voltage and fast turn-on time. Because of these characteristics asynchronous boost converterscan have as good as, or better efficiency, than synchronous boost converters. This is especially true whenthe boost conversion ratios (VOUT/VIN) are high, and the Schottky diode conduction t
  • Power Budget for Backlight Drivers
    PDF, 592 Kb, 档案已发布: Jun 27, 2013
    This application report discusses the Power Budget of an LED backlight driver. It provides experimental and theoretical methods of calculating different losses associated with LED backlight drivers. It also provides an analytical discussion on behavior of different losses vs brightness levels.
