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 | BS | passive | Bootstrap pin. A bootstrap capacitor (typ. 10nF) is connected between BS and SW to generate the gate-drive rail for the internal high-side NMOS switch. Absolute-max voltage is VSW + 6V. |+| 2 | GND | power_in | Device ground return pin. |+| 3 | FB | input | Feedback pin. Connect to an external resistor divider from VOUT to set the output voltage; regulates to VFB = 0.81V (typ). If VFB exceeds ~20% above nominal (~0.972V) OVP triggers; if VFB < 0.25V the oscillator frequency is folded back (~460kHz) for short-circuit protection. Absolute max -0.3V to 6V. |+| 4 | EN | input | Enable/control input. Drive above 1.5V to enable the IC; drive below 0.4V to shut it down (shutdown supply current ~0.1μA typ, 1μA max). Absolute-max voltage -0.3V to VIN+0.3V. |+| 5 | IN | power_in | Supply input pin. Operating range 4.5V-18V (absolute max 20V). A local input decoupling capacitor (typ. 10μF) to GND is required to keep the DC input voltage stable. |+| 6 | SW | power_out | Power switch output. Connects to the external inductor, freewheeling Schottky diode (asynchronous), and bootstrap capacitor. Absolute-max voltage 21V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `AP3211KTR-G1KTR-G1`++## CAD (KiCad official)++- Symbol: `AP3211KTR-G1`+- 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:** [Diodes Incorporated datasheet](https://www.diodes.com/assets/Datasheets/AP3211KTR-G1.pdf) (11 pp, sha256 `e19ceaa554a5443e`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
