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 | Chip Enable input. Drive above 1.5V (VENH) to turn on the converter; drive below 0.4V (VENL, 0.3V typ) to shut it down (<1µA shutdown current). Do not leave floating. |+| 2 | GND | power_in | Analog ground pin. Common return for the IC and the input/output decoupling capacitors. |+| 3 | SW | output | Power switch output; switch node connecting to the external inductor. Tied to the drains of the internal P-channel and N-channel MOSFET switches. RDS(on) ~300mΩ typ, peak current limit 2A. |+| 4 | VIN | power_in | Power supply input, 2V to 6V (6.5V abs max). Must be closely decoupled to GND with a 4.7µF or greater ceramic capacitor. |+| 5 | FB | input | Output voltage feedback input. External resistor divider (R1/R2) from VOUT sets the output voltage per VOUT = 0.6V * (1 + R1/R2). Internal reference VFB = 0.600V (±2%). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Unknown |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## CAD (KiCad official)++- Symbol: `MT3406`+- 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:** [Unknown datasheet](docs/mt3406-datasheet.pdf) (9 pp, sha256 `b0ca202562d99c5f`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
