By integrating three independent LED drivers, the LTR3496 offers a highly effi cient, compact and cost-effective solution to drive multiple LED strings. All three drivers have independent on/off and PWM dimming control, and can drive different numbers or types of LEDs. High side current sensing and built-in gate drivers for PMOS LED disconnect allow the LT3496 to operate in buck, boost, SEPIC or buck-boost modes with up to 3000:1 True Color PWM™ dimming ratio.Triple LED Driver in 4mm × 5mm QFN Supports LCD
Backlights in Buck, Boost or Buck-Boost Modes and
Delivers 3000:1 PWM Dimming Ratio

Introduction Integrated PMOS Drivers Improve PWM Dimming
By integrating three independent LED drivers, the LT3496 Ratio to 3000:1
offers a highly efcient, compact and cost-effective A high PWM dimming ratio is critical in many display
solution to drive multiple LED strings. All three drivers applications, especially in high end LCD panels. Beware,
have independent on/off and PWM dimming control,
