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 | NC | unconnected | No connection. Leave floating or tie to a suitable copper pour for mechanical stability; not internally bonded. |+| 2 | NC | unconnected | No connection. Leave floating; not internally bonded. |+| 3 | NC | unconnected | No connection. Leave floating; not internally bonded. |+| 4 | Feedback | input | Feedback pin (FB). For fixed 5.0 V version this senses the regulated output; internal divider sets Vout. Feedback threshold voltage is 1.23 V referenced to the internal bandgap. Absolute maximum -0.3 V to 25 V. |+| 5 | ON/OFF | input | Enable pin with hysteresis. Drive low (or float, default low) to turn the regulator ON; drive high to shut down. TTL-compatible. Absolute maximum -0.3 V to 25 V. |+| 6 | GND | power_in | Ground return pin. Must be placed outside the Schottky diode and output capacitor ground path in the PCB layout to prevent switching current spikes from coupling noise into the regulator. |+| 7 | VIN | power_in | Supply voltage input. HV variant operates from 4.5 V to 60 V DC. Bypass VIN to GND with a suitably large low-ESR capacitor (typ. 470 uF/35 V+) placed close to the pin to filter input ripple. |+| 8 | Output | output | Power switch output (SW node). Internal NPN power transistor emitter/collector node that drives the external inductor and Schottky catch diode. Supports up to 1.5 A continuous output current. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOP-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `LM2594HVM-5.0M`++## CAD (KiCad official)++- Symbol: `LM2594HVM-5.0`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/lm2594hvm-5-0-datasheet.pdf) (17 pp, sha256 `b4935ffaa609c227`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
