It integrates a 1.5A switch and supports both step-down (buck) and step-up (boost) topologies, making it suited for single-string LED backlight applications in displays ranging from small panels to automotive infotainment screens. The part accepts a supply from 3V to 30V, covering common 5V, 12V, and 24V rails without an external bias regulator. Operating junction temperature range is -40°C to 125°C. ## 1.5A switch current — what it means for your LED string The 1.5A switch current is the peak the internal FET can handle. ## Lifecycle and sourcing reality The LT3517IFE#PBF is listed as Active with ROHS3 compliance.","metaTitle":"LT3517IFE#PBF DC-DC Regulator LED Driver, 1.5A Switch","metaDescription":"LT3517IFE#PBF DC-DC regulator LED driver from Analog Devices, True Color PWM series.
