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 | PGOOD | output | Power Good window comparator open-drain output that must be pulled up to 5 V or an appropriate signal voltage, with continuous sink capability of 1 mA; it goes high 1 ms after VFB is within limits and goes low after a 2-µs delay when power is bad. |+| 2 | TRIP | input | Overcurrent-limit (OCL) detection threshold setting pin, sourcing 10 µA at room temperature with a 4700 ppm/°C temperature coefficient, where 0.2 V ≤ VTRIP ≤ 3 V sets the OCL trip voltage. |+| 3 | EN | input | SMPS enable pin; short to GND to disable the device. |+| 4 | VFB | input | SMPS feedback input to which the feedback resistor divider is connected. |+| 5 | TST | input | Test pin used for production-line testing only; pull down to GND with a resistor of 470 kΩ or less. |+| 6 | DRVL | output | Synchronous MOSFET gate driver output, referenced to GND and driven from the V5IN voltage. |+| 7 | V5IN | power_in | 5-V supply input with +30%/-10% tolerance, which also feeds the internal bootstrap MOSFET switch; recommended operating range is 4.5 V to 6.5 V. |+| 8 | SW | input | Switch node serving as the high-side MOSFET gate drive return, used for on-time generation and output discharge; recommended input range is -1 V to 28 V (-4 V to 28 V for transients under 30% of the period). |+| 9 | DRVH | output | High-side MOSFET gate driver output, floating on the SW node, with gate drive voltage defined by the VBST-to-SW bootstrap capacitor voltage. |+| 10 | VBST | input | Supply input for the high-side MOSFET driver (bootstrap); connect a flying capacitor from this pin to SW, with the pin internally connected to V5IN through the bootstrap MOSFET switch. |+| 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(3x3) |+| Category | Power Management (PMIC) |+| Pins | 11 |++## CAD (KiCad official)++- Symbol: `TPS51211DSCR`+- Footprint: `Package_SON:VSON-10-1EP_3x3mm_P0.5mm_EP1.2x2mm`+- 3D model: WSON-10-EP(3x3) (KiCad packages3D, STEP)+- 3D model files: `tps51211dscr-etched.step` / `tps51211dscr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps51211dscr.step` / `tps51211dscr.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/tps51211) (30 pp, sha256 `ee7b7bc90fd35a3d`, retrieved 2026-10-08, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-5-5` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
