# BarbellAI Puck V1 Radar Core ## Description Low-noise 1.3V buck regulator for the 1P3_RF rail, 3A output, VBATT input, QFN RPU 10-pin 2.0x2.0mm ## Project Details - **Owner:** mowens96531 - **Created:** 4/22/2026 - **Last Updated:** 5/6/2026 - **Visibility:** Public - **Power Requirements:** 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. - **Manufacturer Name:** Texas Instruments - **Allow Substitutes:** Do not regress to the retired U5/TPS7A2013PDBVR LDO plan unless explicitly requested. Authoritative implementation uses U6 TPS62913RPUR for 1P3_RF. - **Implementation Details:** 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 Any earlier references to U5 as an LDO or to TPS7A2013PDBVR are superseded and must not be reinstated unless explicitly requested. - **Part Type:** Low-noise buck - **Package or Case Code:** QFN RPU 10-pin 2.0x2.0mm - **Manufacturer Part Number:** TPS62913RPUR ## Key Components ### CL_BLE_1 — [Generic Capacitor](https://www.flux.ai/jharwinbarrozo/generic-capacitor~1d.md) - Role Details: 12pF load capacitor from U_BLE P0.00 XL1 to GND - Capacitor Type: C0G/NP0 ceramic - Part Type: Non-Polarized Capacitor - Role: Timing - Package: SMD_0603_1608Metric - Capacitance: 12pF - Package or Case Code: 0402 **Pins:** - P1 [pin 1] - P2 [pin 2] ### CL_BLE_2 — [Generic Capacitor](https://www.flux.ai/jharwinbarrozo/generic-capacitor~1d.md) - Capacitance: 12pF - Capacitor Type: C0G/NP0 ceramic - Role: Timing - Role Details: 12pF load capacitor from U_BLE P0.01 XL2 to GND - Part Type: Non-Polarized Capacitor - Package: SMD_0603_1608Metric - Package or Case Code: 0402 **Pins:** - P1 [pin 1] - P2 [pin 2] ### D_LED — [150080M153000](https://www.flux.ai/adrian95/150080m153000~ipz.md) - Part Type: LED - Role Details: Common anode to 3V3_BLE, cathodes sink via U_BLE GPIO through 470 ohm resistors - Role: RGB status LED - Manufacturer Part Number: 150080M153000 - Manufacturer Name: Würth Elektronik - Datasheet URL: https://www.we-online.com/components/products/datasheet/150080M153000.pdf - License: https://creativecommons.org/licenses/by/4.0/ **Pins:** - + [pin 4] - B [pin 3] - G [pin 2] - R [pin 1] ### FB1 — [Generic Inductor](https://www.flux.ai/jharwinbarrozo/generic-inductor~wlv.md) - Inductance: 13.5nH - Role: Ferrite Filter - Part Type: Inductor - Role Details: Ferrite-bead second-stage output filter between VOUT_STAGE1 and 1P3_RF; specified as 600 ohms at 100 MHz. - Package: SMD_0603_1608Metric **Pins:** - P1 [pin 1] - P2 [pin 2] ### IC1 — IWR6843ARQGALP rvyp - Manufacturer Part Number: IWR6843ARQGALP - Part Type: Sensors - Role Details: IWR6843ARQGALP AoP radar SoC on ALP180A.
