BarbellAI Puck V1 Radar Core
Properties
Three regulated rails required: 1.8V first, 1.3V VDD_CORE second via TPS62810-class buck, 1.2V RF third. Authoritative 1P3_RF implementation: U6 TPS62913RPUR low-noise buck drives 1P3_RF directly from VBATT. U5 is retired. Sequencing must follow 1.8V -> 1.3V -> 1.2V with power-good gating. SYS_RESET_N must remain low until all three rails are stable.

Do not regress to the retired U5/TPS7A2013PDBVR LDO plan unless explicitly requested. Authoritative implementation uses U6 TPS62913RPUR for 1P3_RF.
Authoritative MCP rail mapping: U1 TPS62810QWRWYRQ1 -> 1P2_CORE only for IC1 VDDIN/VIN_SRAM/VNWA; U6 TPS62913RPUR low-noise buck -> 1P3_RF directly from VBATT; U2 TPS7A8400RGRT configured to 1.8V -> 1P8_ANA only for IC1 VIOIN_18/VIN_18CLK/VIOIN_18DIFF/VIN_18BB/VIN_18VCO. U5 is retired. Any earlier references to U5 as an LDO or to TPS7A2013PDBVR are superseded and must not be reinstated unless explicitly requested.
