LM2576HVS-12

TECH PUBLIC · DC-DC Converters · TO-263-5L

LM2576HVS-12 from TECH PUBLIC, in a TO-263-5L. 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 VIN power_in Unregulated input supply. Operating range up to 60V (63V absolute max). Bypass locally with a 100uF/75V aluminum electrolytic close to the pin.
2 OUTPUT output Switch (SW) output pin. Internal power switch node that drives the external inductor and catch diode. Saturation voltage typ 1.4V at 3A; supports up to 3A load with 12V fixed output.
3 GND power_in Device ground reference. Also the thermal path for the TO-263 tab; connect to a ground plane for heat dissipation.
4 FEEDBACK input Regulation feedback input. On the fixed 12V version this pin connects directly to the regulated output to sense 12V. Internal reference is 1.23V (ADJ version divider tap).
5 ON/OFF input Active-low TTL-compatible enable/shutdown input. Logic low (<=0.8V) enables the regulator; logic high (>=2.4V, up to VIN) puts it in low-power standby (typ 50uA). Do not exceed VIN.

Ordering variants

Same part, different packaging or reel option.

  • LM2576HVS-12

CAD (KiCad official)

  • Symbol: LM2576HVS-12
  • Footprint: Package_TO_SOT_SMD:TO-263-2
  • 3D model: TO-263-5L (KiCad packages3D, STEP)
  • 3D model files: lm2576hvs-12-etched.step / lm2576hvs-12-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm2576hvs-12.step / lm2576hvs-12.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
lm2576hvs-12.step 180 KB You want the bare part, or you mark your own boards.
lm2576hvs-12-etched.step 1.9 MB You want the part with LM2576HVS-12 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 528 faces against 135 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.
