LED Driver Support Functions
Analog Devices LED driver support functions include matrix LED dimmers, a PWM generator, and LED ballasters targeted for automotive, display backlighting, handheld, and general lighting applications. Matrix LED dimmers operate in conjunction with an LED driver circuit configured as a current source, enabling individual LEDs within a string to be turned on and off. Fade transition between PWM dimming states offers more flexibility in designing matrix lighting with smoother dimming transitions. The programmable switching frequency of the matrix LED dimmer included in this LED Driver support function category helps to optimize efficiency and avoid critical frequency bands, including AM radio.
