Fairchild's family of tightly matched, binned LEDs, in conjunction with complementary LED driver ICs, provide a range of matching and brightness control in cellular phones, PDAs, and other portable applications. These LEDs run directly from the battery, with no boost required. The QTLP6XX series of low VF surface mount LEDs feature low voltage operation for low power consumption and a narrow forward voltage range. the FAN56XX LED Driver ICs offer a variety of drive options. They eliminate the need for external current matching resistors.
