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 | SW | output | Switching node. Drain of the internal 4A NMOS power switch; connects to the boost inductor and Schottky rectifier. Carries the high-frequency switching waveform (1.2MHz) and must be routed short and isolated from sensitive nets. Absolute max 28V, RDS(on) ~80mΩ. |+| 2 | GND | power_in | Ground reference for the device. Return path for the power switch and internal control circuitry. |+| 3 | FB | input | Feedback input to the error amplifier. Connect a resistor divider from VOUT to FB to GND to set output voltage: VOUT = 0.6V x (1 + R1/R2). Internal reference VR = 600mV (588-612mV). R1 recommended in the hundreds-of-kΩ range. |+| 4 | EN | input | Chip enable, active high. VENH >= 1.2V enables the converter; VENL <= 0.5V shuts it down (IOFF <= 1µA). Do not leave floating. |+| 5 | VIN | power_in | Supply/bias input for internal control circuitry. Operating range 2-24V (UVLO ~1.7-2V). Requires a 1uF ceramic decoupling capacitor to GND close to the pin. May be tied to VIN or to VOUT; when VIN < 5V, tying pin 5 to VOUT is recommended to strengthen gate drive. |+| 6 | NC | unconnected | No connect. Leave floating. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HX hengjiaxing |+| Package | SOT-23-6L |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `HX3608AR`+- `HX3608AL`++## CAD (KiCad official)++- Symbol: `HX3608`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HX hengjiaxing datasheet](docs/hx3608-datasheet.pdf) (6 pp, sha256 `c124e6edb58bd1df`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
