LED Driver IC Procurement Notes

Verify the specific suffix E11 against the official datasheet to confirm pinout and internal configuration, as TI uses suffixes to denote variant differences. Ensure the DSBGA-20 package footprint matches your PCB design constraints. Confirm RoHS compliance status directly from the manufacturer's documentation before finalizing procurement.

LED Driver IC Selection Notes

Select this component when a compact solution for driving multiple LEDs with precise I2C control is required. The DSBGA-20 package offers space savings compared to larger packages. Consider the 23 mA output limit and 20 V maximum input voltage when designing the power stage. Verify that the available switching frequencies meet your electromagnetic interference requirements.

LED Driver IC Part Context

This part belongs to the LP8556 series of LED lighting drivers from Texas Instruments. The series includes various variants differentiated by suffix codes, such as E01, E03, E04, E05, and E09. These variants share core functionalities but may differ in specific electrical characteristics or packaging details. The LP8556 family is targeted at display backlighting and general LED illumination markets.

LED Driver IC Replacement Considerations

Other LP8556 variants like LP8556TMX-E09/NOPB or LP8556TME-E05/NOPB are functionally similar but require verification of the specific suffix parameters. Cross-referencing the datasheet for each candidate is essential to ensure compatibility with the existing circuit design.
