Pin Function Grouping


Grouped all 11 pins by function:
  • Power: VIN, VCC
  • Power Stage: BOOT, SW pins, VOUT
  • Ground: GND
  • Control: EN, MODE/SYNC
  • Feedback and Status: FB, PGOOD
Pin ordering was also set within each group for consistent parametric-symbol layout.
Assign a Terminal Order from 1 to 10, starting with Power. Power should be Terminal Order 1, and Ground should be last, Terminal Order 10. For Orientation, set Power to "Top" and Ground to "Bottom." For the remaining sections/groups, you may decide the Terminal Order and Orientation yourself. For Orientation, distribute them between "Left" and "Right" — don't put everything on one side. Each group/section should have a different orientation.
There are 11 physical terminals, but the requested range is 1–10. Also, after Power=Top and Ground=Bottom, there are more remaining groups than the two available orientations (Left/Right), so every group cannot have a unique orientation.
Should I:
  • Give both SW pins the same order so the sequence remains 1–10
  • Alternate the remaining groups between Left and Right?
Assign both SW pins the same order, keep the sequence from 1 through 10, and alternate remaining groups Left and Right.
Assigned Terminal Orders 1–10, with both SW pins sharing order 4. Power pins are oriented Top, Ground is Bottom, and the remaining functional groups alternate between Left and Right.
