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 | passive | Switch node. Boost inductor connection between the internal N-channel low-side switch and P-channel synchronous rectifier. Connect the external boost inductor between VIN and this pin. Absolute maximum -0.3 V to 6 V. |+| 2 | GND | power_in | Device ground. Return for all internal circuitry and reference for feedback and enable thresholds. |+| 3 | EN | input | Enable control input. Logic high (>=70% of VIN) enables the converter; logic low (<=20% of VIN) puts the device into shutdown (typ. 0.6 uA). In the CJ9113T6A shutdown the load is truly disconnected from VIN. Input leakage typ. 5 nA at VEN=5 V. Absolute maximum -0.3 V to 6 V. |+| 4 | VFB | input | Feedback voltage input to the internal error amplifier. Regulates to 1.215 V typical (1.179 V to 1.251 V). Connect to the external resistor divider tap from VOUT to set output voltage. Bias current typ. 10 nA. Absolute maximum -0.3 V to 6 V. |+| 5 | VOUT | power_out | Regulated boost output voltage. Adjustable from 1.8 V to 5.5 V via the external VFB divider. Also serves as the drain connection for the internal synchronous P-channel rectifier. Bypass with a 10 uF ceramic capacitor to GND. Absolute maximum -0.3 V to 6 V. |+| 6 | VIN | power_in | Input supply voltage. Operating range 0.82 V to 5.5 V after start-up (start-up 0.82 V at 1 mA load, minimum operating 0.65 V). Bypass with a 4.7 uF ceramic capacitor to GND. Absolute maximum -0.3 V to 6 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Changjing |+| Package | SOT-23-6L |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `CJ9113T6A`+- `CJ9113T6ACJ9113T6B`++## CAD (KiCad official)++- Symbol: `CJ9113T6A`+- 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:** [Changjing datasheet](docs/cj9113t6a-datasheet.pdf) (9 pp, sha256 `d4b35cd4d97477c8`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
