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 | EN | input | Enable input. Drive high (>=1.5 V) to turn the converter on, low (<=0.4 V) to shut it down. Pin has an internal ~1100 kΩ pull-down to GND. |+| 2 | GND | power_in | Power ground pin. Return for both the internal power MOSFETs and control circuitry. |+| 3 | SW | power_out | Switching node (also labeled LX on the pin diagram). Connect this pin to the external inductor; internal high-side and low-side MOSFETs switch this node between VIN and GND. |+| 4 | VIN | power_in | Power input pin, 2.7 V to 5.5 V. Bypass with a ceramic capacitor (10 µF typical) close to the pin. |+| 5 | FB | input | Output voltage feedback pin. Connect to the midpoint of an external resistor divider from VOUT to GND; internal reference is 0.6 V (0.591 V - 0.609 V). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `AP3429AKTTR-TP`++## CAD (KiCad official)++- Symbol: `AP3429AKTTR-TP`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [TECH PUBLIC datasheet](docs/ap3429akttr-tp-datasheet.pdf) (5 pp, sha256 `40c74d6292c6f140`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
