LM2594HVM-5.0

UMW · DC-DC Converters · SOP-8

LM2594HVM-5.0 from UMW, in a SOP-8. 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.

Ordering variants

Same part, different packaging or reel option.

  • 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)
  • 3D model files: lm2594hvm-5-0-etched.step / lm2594hvm-5-0-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm2594hvm-5-0.step / lm2594hvm-5-0.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm2594hvm-5-0.step 122 KB You want the bare part, or you mark your own boards.
lm2594hvm-5-0-etched.step 2.2 MB You want the part with LM2594HVM-5.0 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 550 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: UMW datasheet (17 pp, sha256 b4935ffaa609c227, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
