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 | ISENSE | input | Current sense input pin. Connects to the drain node of the external PFET so that RDS(on) sensing can be compared against the ADJ threshold for cycle-by-cycle current limiting. |+| 2 | GND | power_in | Signal ground reference for the controller. |+| 3 | NC | unconnected | No internal connection. |+| 4 | FB | input | Feedback input. Connect to a resistor divider between the regulated output and GND to program the output voltage; internal reference is 1.242 V (typical). |+| 5 | ADJ | input | Current-limit threshold adjustment. Sources ~5.5 µA from an internal current source through an external resistor to VIN; the resulting voltage sets the RDS(on)-based over-current trip level compared with the PFET VDS. |+| 6 | PWR GND | power_in | Power ground for the gate driver return current. |+| 7 | PGATE | output | Gate drive output for the external P-channel MOSFET. Output swings between VIN and (VIN − 5 V); source/sink driver resistance ~5.5 Ω / 8.5 Ω. |+| 8 | VIN | power_in | Power supply input pin. Operating range 4.5 V to 35 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VSSOP-8-0.65mm |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `LM3485MMXMM`+- `LM3485MMXMMX`++## CAD (KiCad official)++- Symbol: `LM3485MMX`+- Footprint: `Package_SO:VSSOP-8_2.3x2mm_P0.5mm`+- 3D model: VSSOP-8-0.65mm (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/lm3485mmx.pdf) (28 pp, sha256 `6637528b55f3e979`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
