U3 to IC1 Transfer


Received notification from "TPS63802 Stage 2 Verification" that it finished — picking the work back up.
Phase B has been built. I’m reconciling the executor’s report now, then a fresh reviewer will independently check the destructive switch-node and feedback conditions before I close Stage 2.
Received notification from "TPS63802 Audit" that it finished — picking the work back up.
Stage 2 build is complete:
  • U3 TPS63802DLAT installed and wired
  • L3 replaced with Murata DFE201612E-R47M=P2
  • R13/R25 feedback divider added
  • Critical switch nodes reported correctly separated: U3 pin 7/L3 pin 2=REG_SW2; U3 pin 9/L3 pin 1=REG_SW1
  • PG is explicitly unconnected; PGOOD_N unchanged
  • Initial ERC reported clean
The independent audit finished, but I cannot retrieve and reconcile its final report because no ACUs remain. That reconciliation, the full 12-item report, and final Stage 2 sign-off remain pending; no further project changes should be made until the audit is reviewed.
