Advanced Analogic Technologies, Inc. (AnalogicTech), an analog semiconductor company focused on powering innovative solutions in consumer, industrial, and communications markets, introduced its AAT1409/7/5 family of multi-string LED backlight drivers. Offering integrated boost converters and precision current sinks that can support up to 88 LEDs at 360mA total LED current, the AAT1409/7/5 drivers are among the most powerful in the marketplace. These new drivers bring to market a fully featured solution that reduces the number of backlight PCBs, reducing costs, yet is capable of driving high brightness LEDs and ensuring uniformity across the display by precisely controlling the backlight intensity.
The AAT1409/7/5 drivers operate from DC inputs, cigarette lighter adapters or multi-cell Li-ion batteries over the 4.5V to 26V range. The family is available in 8, 6 and 4 channels making them ideal for driving white LED (WLED) edge backlighting for LCD panels ranging from 10 to 22 inches in size. The drivers also support up to 100 kHz PWM dimming frequency to ensure silent operation.
