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 | CB | passive | Boot-strap capacitor connection for the high-side driver. Connect a high-quality 470-nF capacitor from CB to the VSW pin to develop the boosted gate-drive supply. |+| 2 | NC | unconnected | No connect pin. Leave floating; do not use as a tie point. |+| 3 | NC | unconnected | No connect pin. Leave floating; do not use as a tie point. |+| 4 | FB | input | Feedback sense input pin. For the fixed 5-V version, connect this pin directly to the output capacitor (VOUT). Absolute-maximum feedback pin voltage is -0.3 V to 14 V. |+| 5 | ON/OFF | input | TTL-compatible enable input to the voltage regulator. High = ON and low = OFF; pull high or float to enable the regulator. Input voltage range -0.1 V to 6 V. |+| 6 | GND | power_in | Power ground. Connect to system ground. Return for CIN and COUT; the path from CIN and GND must be as short as possible to minimize switching noise. |+| 7 | VIN | power_in | Supply input pin to the collector of the internal high-side FET. Connect to the input supply (8 V to 40 V recommended) and to the input bypass capacitor CIN; the path from VIN to the high-frequency bypass CIN and GND must be short. Absolute-maximum 45 V. |+| 8 | VSW | output | Source pin of the internal high-side FET; the switching node. Connect to the output inductor and the cathode of the external catch diode. Switch voltage to ground is rated down to -1 V (absolute maximum). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments LM2675MX 5 0 NOPB |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `LM2675MX-5.0MX`+- `LM2675MX-5.0M`+- `LM2675MX-5.0N`+- `LM2675MX-5.0SD`++## CAD (KiCad official)++- Symbol: `LM2675MX-5.0`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments LM2675MX 5 0 NOPB datasheet](https://www.ti.com/lit/ds/symlink/lm2675mx-5.0.pdf) (33 pp, sha256 `324342d0eaad04c2`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
