LED matrix drivers are monolithic high-efficiency LED drivers designed to supply LED arrays used in the backlighting of LCD panels in consumer, industrial and automotive applications.
Housed in compact QFN packages, these ICs integrate a power converter section and a LED array driver section consisting of several PWM-dimmable current generators.
The wide input voltage range covers the most common voltage buses (5 V, 12 V and 24 V).
Additional flexibility is guaranteed by a full set of adjustable protection functions, together with complete and flexible fault management and high switching frequency, to reduce the size and cost of the final application.
