This document introduces the LT®3496 triple LED driver, which can achieve a PWM dimming ratio of up to 3000:1, supports multiple working modes, and is packaged in a 4mm × 5mm QFN package, which is highly efficient, compact, and cost-effective.
This document describes the LT3496, a compact and cost-effective triple independent LED driver integrated into a single 4mm x 5mm QFN package. It is designed to drive multiple LED strings in LCD backlight applications, offering buck, boost, or buck-boost operation with up to 3000:1 True Color PWM dimming ratio.
The device delivers a PWM dimming ratio of up to 3000:1.
Each channel drives 500mA of current to its LEDs.
Each string can have from eight to twelve LEDs, depending on type.
