• Supports multiple converter topologies including Buck, Boost, and Buck-Boost configurations
• Enables precise light control through combined analog and PWM dimming interfaces

LED Driver IC Applications

• LED backlighting systems
• General LED lighting drivers
• Industrial illumination applications

LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence when sourcing. Confirm the package type matches the 16-TSSOP specification with an exposed thermal pad for proper heat dissipation. Ensure the supplier provides official documentation to validate the component's authenticity and manufacturing origin.

LED Driver IC Selection Notes

Select this component for designs requiring a single-output driver with flexible topology options. It is suitable for applications needing high current capability up to 2.3A. Consider the wide input voltage range for varying supply conditions. Evaluate the thermal requirements associated with the TSSOP-EP package for adequate heat management in enclosed spaces.

LED Driver IC Part Context

This part belongs to the LT3518 family of LED drivers from Analog Devices. It is distinct from similar models like the LT3519 which may feature integrated Schottky diodes or different output currents. The HFE variant specifically denotes the 16-TSSOP package configuration used in compact surface-mount designs.

LED Driver IC Replacement Considerations

Direct substitutes include other LT3518 variants such as LT3518EFE#TRPBF, which shares identical electrical characteristics but differs in packaging format. Verify pin compatibility and thermal performance when considering alternative packages within the same functional family.
