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 | BST | passive | Bootstrap pin. Connect a 100nF ceramic capacitor from BST to SW to generate the boosted gate-drive rail for the high-side N-channel MOSFET (charged to ~4.0V above SW when SW is low). |+| 2 | GND | power_in | Ground return for the device. Also serves as the PGND for the low-side power switch; connect directly to a solid ground plane. |+| 3 | FB | input | Feedback input to the internal transconductance error amplifier. Connect an external resistor divider from VOUT to FB to GND to set the output voltage; internal reference V_REF = 0.8V (typ, 0.776-0.824V). |+| 4 | EN | input | Enable input. Drive high (V_ENH ≥ 1.3V typ) to enable the regulator; drive low (V_ENL ≤ 1.2V typ, shutdown below 0.3V) to disable. Absolute max rating V_SS-0.3 to V_SS+45V allows tying through a divider from V_IN for programmable UVLO. Input current ≈2µA at 5V. |+| 5 | VIN | power_in | Supply voltage input, 4.5V to 40V operating range (45V abs max). Bypass with a 22µF ceramic capacitor to GND placed close to the pin, plus an optional 0.1µF for high-frequency filtering. |+| 6 | SW | output | Switch node - the common drain of the integrated high-side and low-side N-channel power MOSFETs (R_DSON_H ≈ 450mΩ, R_DSON_L ≈ 270mΩ). Connect the external inductor between SW and the regulator output. SW absolute range V_SS-0.3 to V_IN+0.3V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `TP6841S6S6`++## CAD (KiCad official)++- Symbol: `TP6841S6`+- 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:** [TECH PUBLIC datasheet](docs/tp6841s6-datasheet.pdf) (9 pp, sha256 `5c91752cf208f8c4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
