Part Review and Datasheet Update

flux

I reviewed the part project and compared it to the official TI datasheet. The audit followed the standard part-project datasheet-sync workflow: verify metadata first, then compare terminal definitions and footprint pad coverage against the datasheet pin table

Symbol vs datasheet pinout
The schematic symbol has all 6 required terminals, and the pin numbers match the datasheet exactly.

Footprint vs datasheet
The footprint contains 6 pads, one for each required pin:
VIN, SW, GND, BOOT, EN, FB.

Part type metadataNeeded normalization to Buck ConverterFixed
Footprint geometry dimensionsPad existence is correct, but exact land pattern dimensions were not exposed by the project data I can read hereReview manually if you want full package-land-pattern validation
Recommended pin typing
Based on the datasheet pin functions, these should be the terminal types:

Summary
  • The official datasheet URL was already present, so no datasheet-URL update was needed.
  • The symbol is structurally correct: all 6 pins exist and match the datasheet numbering.
  • The footprint appears complete at the pad-count/name level.
  • The biggest remaining issues are metadata completeness on the terminals:
    • pin types are unset
    • pin descriptions are missing
  • I also corrected the project metadata for Package or Case Code and Part Type to match the datasheet.
If you want, I can next populate the terminal properties for VIN, SW, GND, BOOT, EN, and FB with correct pin types and short pin descriptions from the datasheet.
