LM2596-5.0FW05ARHQ

GR · DC-DC Converters · TO-263-5

LM2596-5.0FW05ARHQ from GR, in a TO-263-5. 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 Positive input supply for the IC switching regulator. Operating range 4.5 V to 40 V (45 V absolute maximum). A suitable input bypass capacitor (e.g. 470 μF, 50 V) must be present at this pin to minimize voltage transients and supply the switching currents required by the regulator.
2 Output output Internal power switch output (emitter of the 3 A internal NPN switch). The voltage at this pin switches between approximately (+VIN − VSAT, VSAT ≈ 1.5 V at 3 A) and approximately −0.5 V with a duty cycle of VOUT/VIN. Connect to the catch diode and inductor of the buck output stage; keep the PCB copper area on this node small to minimize EMI coupling.
3 GND power_in Circuit ground return for the IC. On the TO-263 package the metal tab is internally connected to GND and serves as the primary thermal path to the PCB copper plane.
4 Feedback input Senses the regulated output voltage to complete the internal feedback loop. On the fixed 5 V version this pin is tied directly to the regulated 5 V output through the application circuit (internal divider sets 5 V ±4% over line/load). Absolute maximum feedback pin voltage is −0.3 V to 25 V.
5 ~{ON}/OFF input Active-low TTL-compatible shutdown control. Pulling this pin below ~1 V (VIH threshold typ 1.3 V) turns the regulator on; pulling it above ~1.3 V (up to 25 V max) shuts the regulator down, dropping total input supply current to ~80 μA standby. Input current is ~10 μA at 2.5 V. If shutdown is not used, tie to GND or leave open (regulator will be ON).

File Size Use it when
lm2596-5-0fw05arhq.step 180 KB You want the bare part, or you mark your own boards.
lm2596-5-0fw05arhq-etched.step 2.9 MB You want the part with LM2596-5.0FW05ARHQ already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 747 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.
