应用须知

  • 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.
  • Analog PWM Dimming in White-LED Drivers
    PDF, 539 Kb, 档案已发布: Dec 21, 2016
    Pulse-width modulation (PWM) is a common type of dimming used to adjust the current in white-LEDdriver devices. PWM dimming takes a rectangle waveform with variable positive duty cycle (D) and adjuststhe LED current proportionally. For many smaller format white LED drivers (7-inch screen size or smaller),the PWM signal is converted to a DC control voltage and made to drive the LED current in
