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 | BOOT | power_out | Bootstrap capacitor connection for the high-side MOSFET gate driver; connect a quality 0.1 µF X7R or X5R capacitor rated 16 V or higher between BOOT and SW. |+| 2 | VIN | power_in | Supply input for the regulator, operating from 4 V to 40 V; the path from VIN to the high-frequency bypass capacitor CIN and GND must be kept as short as possible. |+| 3 | VIN | power_in | Supply input for the regulator (second VIN pin, same connection as pin 2), operating from 4 V to 40 V; keep the path to CIN and GND as short as possible. |+| 4 | EN | input | Enable input with an internal pull-up current source; pulling it below 1.2 V disables the device, while leaving it floating or tying it to VIN enables it, and two resistors can set the input UVLO. EN absolute maximum is 44 V and recommended range is 0 V to 40 V. |+| 5 | RT/SYNC | input | Timing resistor connection or external clock input that sets the switching frequency (200 kHz to 2.5 MHz in RT mode, 250 kHz to 2.3 MHz when synchronized); it must not be left floating or shorted to ground, and a clock with high level ≥1.7 V, low level ≤0.5 V and pulse width >30 ns is required for sync. |+| 6 | SS | input | Soft-start control pin; a capacitor from SS to GND sets the soft-start time using the internal ~3 µA charge current, and for the WSON package the maximum CSS is 4.7 nF. |+| 7 | FB | input | Feedback input connected to the output divider that sets VOUT (VREF typically 0.75 V); connect directly to VOUT for a fixed output, and do not short this pin to ground during operation. The recommended FB range is 0 V to 5 V. |+| 8 | PGOOD | output | Open-drain power-good flag that needs a pull-up of 10 kΩ to 100 kΩ to a logic rail or DC voltage, and the voltage on this pin must never exceed 7 V. |+| 9 | GND | power_in | System ground pin for the regulator, to be connected to the system ground plane. |+| 10 | SW | output | Regulator switching output, internally connected to the low-side power MOSFET, which connects to the power inductor; SW is rated from -3 V to 44 V. |+| 11 | Thermal Pad | power_in | Exposed thermal pad that is the main heat-dissipation path from the die; it must be connected to a ground layer on the PCB. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | WSON-10-EP(4x4) |+| Category | Power Supply Chip |+| Pins | 11 |++## CAD (KiCad official)++- Symbol: `LMR14020QDPRTQ1`+- Footprint: `Package_SON:WSON-10-1EP_4x4mm_P0.8mm_EP2.6x3mm`+- 3D model: WSON-10-EP(4x4) (KiCad packages3D, STEP)+- 3D model files: `lmr14020qdprtq1-etched.step` / `lmr14020qdprtq1-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lmr14020qdprtq1.step` / `lmr14020qdprtq1.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/lmr14020-q1) (37 pp, sha256 `6e24800c10410b48`, retrieved 2026-10-08, tier: lcsc)+- **Datasheet language:** Chinese.
