Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | GND | power_in | Ground pin. Source terminal of the low-side power NFET as well as the ground terminal for controller circuit. Connect sensitive VFB return to this GND at a single point. |+| 2 | SW | output | Switch node connection between the high-side NFET and low-side NFET. Connect the external inductor here. Rated -0.3 V to 30 V (abs max). |+| 3 | VIN | power_in | Input voltage supply pin (4.5 V to 28 V operating; 30 V abs max). Drain terminal of the high-side power NFET. Bypass with a local ceramic capacitor to GND. |+| 4 | FB | input | Converter feedback input to the error amplifier. Connect to the output voltage through a resistor divider; internal reference VFB = 0.596 V (typ). |+| 5 | EN | input | Enable input. Float (leave open) to enable the converter; pull to GND to disable. Rising threshold 1.21 V (typ), falling 1.19 V (typ); abs max 7 V. |+| 6 | BOOT | power_out | Bootstrap supply for the high-side NFET gate drive circuit. Connect a 0.1-µF ceramic capacitor between BOOT and SW. Abs max BOOT-SW = 7 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `TPS54202DDCRDDCR`++## CAD (KiCad official)++- Symbol: `TPS54202DDCR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tps54202ddcr.pdf) (28 pp, sha256 `a7f9b762dcd5e18e`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
