Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VINLDO12 | power_in | Analog power input for internal functions (VREF, BIAS, I2C, logic), always powered. |+| 2 | SYNC | input | Frequency synchronization input that lets an external clock synchronize the internal oscillator; it defaults OFF and must be grounded when not used. |+| 3 | NPOR | output | Open-drain power-on reset output for Buck1 and Buck2 that is pulled to ground when those supplies are not good and requires an external 100-kΩ pullup. |+| 4 | GND_SW1 | power_in | Buck1 NMOS power ground. |+| 5 | SW1 | output | Buck1 switcher output pin. |+| 6 | VIN1 | power_in | Power input from a DC source or battery to Buck1. |+| 7 | ENSW1 | input | Enable input for Buck1; a logic HIGH enables Buck1, and the pin cannot be left floating. |+| 8 | FB1 | input | Buck1 input feedback terminal. |+| 9 | GND_C | power_in | Non-switching core ground pin. |+| 10 | AVDD | power_in | Analog power for the buck converters, always powered. |+| 11 | FB2 | input | Buck2 input feedback terminal. |+| 12 | ENSW2 | input | Enable input for Buck2; a logic HIGH enables Buck2, and the pin cannot be left floating. |+| 13 | VIN2 | power_in | Power input from a DC source or battery to Buck2. |+| 14 | SW2 | output | Buck2 switcher output pin. |+| 15 | GND_SW2 | power_in | Buck2 NMOS power ground. |+| 16 | ENLDO2 | input | LDO2 enable input; a logic HIGH enables LDO2, and the pin cannot be left floating. |+| 17 | ENLDO1 | input | LDO1 enable input; a logic HIGH enables LDO1, and the pin cannot be left floating. |+| 18 | GND_L | power_in | LDO ground pin. |+| 19 | VINLDO1 | power_in | Power input from a DC source or battery to LDO1; if enabled, minimum VIN is 1.74 V. |+| 20 | LDO1 | power_out | LDO1 regulated output. |+| 21 | FBL1 | input | LDO1 feedback input terminal. |+| 22 | FBL2 | input | LDO2 feedback input terminal. |+| 23 | LDO2 | power_out | LDO2 regulated output. |+| 24 | VINLDO2 | power_in | Power input from a DC source or battery to LDO2; if enabled, minimum VIN is 1.74 V. |+| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | WQFN-24-EP(4x4) |+| Category | Power Management (PMIC) |+| Pins | 25 |++## CAD (KiCad official)++- Symbol: `LM26480QSQ-AA`+- Footprint: `Package_DFN_QFN:QFN-24-1EP_4x4mm_P0.5mm_EP2.7x2.7mm`+- 3D model: WQFN-24-EP(4x4) (KiCad packages3D, STEP)+- 3D model files: `lm26480qsq-aa-etched.step` / `lm26480qsq-aa-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm26480qsq-aa.step` / `lm26480qsq-aa.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/lm26480-q1) (42 pp, sha256 `54ee9b099cf1e688`, retrieved 2026-10-08, tier: lcsc)+- **Datasheet language:** Chinese.
