Auto-Frequency Mode Setting for Improved Boost Efficiency in White LED Backlight
PDF, 252 Кб, Файл опубликован: 14 окт 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 Кб, Файл опубликован: 21 дек 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

Schottky Diode Selection in Asynchronous Boost Converters
PDF, 491 Кб, Файл опубликован: 6 сен 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

Inductor Selection in Boost Converters for LCD Backlight Applications
PDF, 764 Кб, Файл опубликован: 24 окт 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.
