LED Driver IC Procurement Notes

Verify the specific suffix configuration when sourcing replacements. The #PBF designation indicates lead-free compliance. Confirm availability status as supply may be limited or subject to factory special orders. Ensure the procurement channel provides valid traceability documentation matching the manufacturer's specifications.

LED Driver IC Selection Notes

Select this component for designs requiring a single-channel 1 A drive capability with wide input voltage tolerance up to 36 V. Consider the exposed thermal pad requirement for adequate heat dissipation in the PCB layout. Evaluate the need for external compensation components based on the desired switching frequency and load characteristics.

LED Driver IC Part Context

This part belongs to the LT3474 series of LED drivers. It serves as a non-pulse-width modulated alternative to variants like the LT3474IFE-1#PBF, which includes additional internal programming options. The standard version focuses on core regulation and protection features without extra configuration pins.
