Part Audit and Datasheet Review

flux

Completed the audit and set the official Analog Devices datasheet URL: https://www.analog.com/media/en/technical-documentation/data-sheets/ltm4712.pdf
Summary:
  • Symbol: 144 terminals match the datasheet 144-ball assignment.
  • Footprint: 144 pads match the CSP_BGA ball count.
  • Key flags: project name uses LTM4712IY-PBF while the official order code is LTM4712IY#PBF; pin descriptions are mostly missing; several pin types should be refined, especially INTVCC, VOUT, and SW1/SW2.
  • Footprint pitch/pad/body dimensions should be spot-checked against the datasheet mechanical drawing before release.

Fix the MPN formatting and missing pin descriptions from the datasheet. Also please convert the symbol to parametric style, and place each pin into the correct section based on the datasheet. also add pin group and pin orientation for all the pins.

flux

I’ll update the official MPN formatting, add datasheet-derived pin descriptions, and restructure the symbol metadata into parametric sections/groups with orientations and ordering.

flux

The official MPN/project name and all unique signal/power-control pins are updated. I’m applying the repeated power/ground ball metadata next, which is the bulk of the 144-ball symbol.

Done.
  • Renamed the project to the official MPN format: LTM4712IY#PBF.
  • Converted the symbol terminals to Parametric style.
  • Added datasheet-derived Pin Description, Section, Pin Group, Pin Orientation, and Terminal Order metadata across the 144-ball symbol.
  • Refined key pin types, including INTVCC as power output, VOUT as power output, and SW1/SW2 as passive switch/test nodes.
  • Verified representative signal, power, switch, SGND, and GND pins; no missing parametric metadata was surfaced by the project index or review checks.
