Looking at the datasheet of this component, can you group together pins by their functions? for example for Power, VDD_1, gnd_1 gnd_2 etc Also can you place them into their respective sections based on their functions NOTE: If you group them, can you not add the same pin if you already added them in a group? You should know which pin function is common for its function

I’ll extract the TPS259850RQPR pin table from the datasheet, compare it with the current part pins, then update each pin’s group/section so each pin appears in only one functional group.

Done. I grouped all TPS259850RQPR terminals by datasheet function and placed them into functional sections without assigning any terminal to more than one group.
Key groups applied:
  • Power Input: VIN_1–VIN_4
  • Power Output: VOUT_1–VOUT_4
  • Controller Power: VDD_1, VDD_2
  • Ground: GND_1, GND_2
  • Comparator: CMPOUT_1, CMPOUT_2, CMPM, CMPP
  • Current Sense and Limit: IMON, ILIM, IREF_1, IREF_2
  • Startup and Timing Control: DVDT, ITIMER
  • Monitoring Outputs: TEMP
  • Mode and Enable Control: MODE, EN/UVLO, SWEN
  • Status and Fault Outputs: PG, ~FLT
  • Do Not Connect: DNC_1, DNC_2
I also updated pin descriptions and normalized electrical pin types where appropriate.
