  • Auto-Frequency Mode Setting for Improved Boost Efficiency in White LED Backlight
    PDF, 252 Kb, Archivo publicado: oct 14, 2016
    As the load current of a boost converter is reduced, the ratio of conduction losses to switching lossesbegins to lower. Conduction losses are losses that are a function of current. Switching losses are lossesthat are a function of switching frequency. As this ratio is reduced the boost switching losses begin todominate the total circuit losses. When this happens, the benefit of lowering the
  • Analog PWM Dimming in White-LED Drivers
    PDF, 539 Kb, Archivo publicado: dic 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
