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
