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 | SW | output | Switching node internally connected to buck switch source; connect to inductor, free-wheeling diode, and bootstrap capacitor. |+| 2 | BST | input | Bootstrap pin; connect capacitor from SW to BST pin; capacitor is charged from VCC through internal diode during buck switch OFF-time. |+| 3 | ISEN | input | Current sense input; inductor current flows through internal sense resistor and out through ISEN pin to free-wheeling diode during buck switch OFF-time; current limit comparator keeps buck switch off if ISEN current exceeds 1.25 A typical. |+| 4 | SGND | power_in | Current sense ground; recirculating current flows into this pin through current sense resistor. |+| 5 | RTN | power_in | Ground return for all internal circuitry other than current sense resistor; input bypass capacitors should be located close to VIN and RTN pins. |+| 6 | FB | input | Voltage feedback input from regulated output to regulation and overvoltage comparators; FB pin regulation level is 2.5 V. |+| 7 | SS | input | Soft start pin; internal 11.5-µA current source charges SS pin capacitor to 2.5 V to softstart the reference input of regulation comparator. |+| 8 | RON/SD | input | ON-time control and shutdown pin; external resistor from VIN to RON/SD sets buck switch ON-time; grounding this pin shuts down the regulator. |+| 9 | VCC | power_in | Bias regulator output nominally equal to VIN for VIN < 8.9 V and regulated at 7 V for VIN > 8.9 V; connect 0.47-µF or larger capacitor from VCC to ground; external voltage can be applied to reduce dissipation if VIN > 8.9 V. |+| 10 | VIN | power_in | Input power supply with nominal range 6 V to 42 V; input bypass capacitors should be located close to VIN and RTN pins. |+| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | WSON-10-EP(4x4) |+| Category | Power Management (PMIC) |+| Pins | 11 |++## CAD (KiCad official)++- Symbol: `LM25010SDX`+- Footprint: `Package_SON:WSON-10-1EP_4x4mm_P0.8mm_EP2.6x3mm`+- 3D model: WSON-10-EP(4x4) (KiCad packages3D, STEP)+- 3D model files: `lm25010sdx-etched.step` / `lm25010sdx-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm25010sdx.step` / `lm25010sdx.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/lm25010-q1) (35 pp, sha256 `d5d36a8196d36262`, retrieved 2026-10-06, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-4-5-20251001` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
