LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the 28-TSSOP-EP package type matches your PCB footprint requirements. Check official datasheets for any recent Product Change Notifications regarding bond wire changes or material declarations. Ensure the supplier provides valid traceability documentation for the Analog Devices Inc. manufacturer origin.

LED Driver IC Selection Notes

Choose this component when designing LED drivers requiring input voltages up to 100V. Select for applications needing simultaneous analog and PWM dimming control. Consider the exposed pad thermal performance for high-power dissipation scenarios. Verify that the 100kHz to 1MHz frequency range aligns with your EMI constraints and inductor selection criteria.

LED Driver IC Part Context

This part belongs to the LT3796 family, which includes variants like LT3796IFE and LT3796HFE. These controllers are engineered for high-voltage LED applications. The EFE suffix typically denotes a specific temperature grade and package variant within the broader product line, sharing core functional architecture with other family members while differing in environmental ratings.

LED Driver IC Replacement Considerations

LT3796EFE#TRPBF offers identical functionality in tape-and-reel packaging instead of tubes.
