LED + LED Driver IC Solutions
Enable direct drive, small footprint and high efficiency brightness control
Fairchild is addressing emerging display application trends by offering combinations of low VF LEDs and low dropout LED driver ICs for the most complete choice of backlighting options available in the industry. Fairchild's growing family of tightly matched (binned) LEDs, in conjunction with complementary LED driver ICs, give designers a full range of matching and brightness control in cellular phones, PDAs, pagers and other ultraportable applications. Unlike the competition, Fairchild's low-voltage LEDs run directly from the battery (no boost required), ultimately reducing part-count and cost.
With expertise in both LEDs and LED driver ICs, Fairchild offers designers the freedom to match an array of LED products in a variety of popular backlighting colors, including white, pink, blue and amber, to their driver ICs. This combination of parts assures precise brightness matching and enables the use of a range of LEDs from matched (binned) LEDs to unmatched LEDs.
