- Analog PWM Dimming in White-LED DriversPDF, 539 Kb, Datei veröffentlicht: 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
