Product details

What the LT3517IFE#PBF is and where it fits

The LT3517IFE#PBF is a DC-DC regulator LED driver from Analog Devices, part of the True Color PWM™ family. 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.

Frequently asked questions

What is the LT3517IFE#PBF used for?

It is a DC-DC regulator LED driver designed for backlight applications. Typical uses include LCD backlighting in automotive infotainment displays, industrial HMI panels, and outdoor signage. It drives a single string of LEDs with constant current, using buck or boost topology depending on the input-to-output voltage relationship.
