Supports external PWM dimming signals for precise light intensity control
Includes internal protection mechanisms against open LED conditions

LED Driver IC Applications

LED backlighting systems
General LED lighting fixtures
Automotive interior illumination

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm that the part number corresponds to the -1 variant which may have distinct electrical characteristics compared to standard versions. Ensure compatibility with the intended thermal management solution due to the exposed pad requirement on the TSSOP-16EP package.

LED Driver IC Selection Notes

Select this component for applications requiring a single-channel constant current source with wide input voltage flexibility. Consider the adjustable frequency range to optimize external passive component sizes. Verify that the operating temperature range meets the environmental requirements of the target application.

LED Driver IC Part Context

This part belongs to the LT3474 series of LED drivers. It shares architectural similarities with other buck-based LED controllers from Analog Devices but is distinguished by its specific pinout and feature set tailored for single-string LED drives. The -1 suffix typically denotes a specific version or revision within the product family.
