Application Notes
- Auto-Frequency Mode Setting for Improved Boost Efficiency in White LED BacklightPDF, 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 DriversPDF, 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
