Work done
  • Removed optional bulk capacitors: C4, C10
  • Downsized passives (0201 preferred; 0402 kept where higher effective C is needed):
  • Normalized passive properties (Capacitance/Resistance formatting, Package, Role/Role Details) on the above parts
Success criteria review
  • ✅ Optional bulk capacitors removed: C4, C10
  • ✅ Remaining passives migrated to smallest packages feasible (0201 where feasible; 0402 retained for the 10 uF “critical” caps)
  • ✅ Existing net connectivity preserved (no net rewiring performed; caps/resistors remain on VIN, +1V2, +1V8, U2_VOUT_NEG, GND as before)
  • ❌ ERC still flags “Missing Power” on U2, U3, U5 (this appears to be a pin-type/power-flag issue, not a disconnected net)
Next steps
  • I can clear the ERC “Missing Power” by adding the proper power-driving flag/source on VIN (and any other rails ERC considers “inputs”). Tell me if you want me to add a power flag / power source symbol to the VIN net.

Target: JLC/LCSC-friendly passives in 0201/0402 only. Voltage derating policy: 3.3 V <= 60% of Vrated -> Vrated >= 5.5 V (use 6.3 V min; 10 V required for LM27761 flying cap and CPOUT). Note DC-bias: 10 uF 0402 X5R/X7R may de-rate significantly; verify effective capacitance at applied bias.
