ETA3458FSG

etasolution · DC-DC Converters · SOT-563

ETA3458FSG from etasolution, in a SOT-563. 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 GND power_in Ground return for the device. Connect to the system ground plane with low-impedance path close to the input capacitor.
2 SW output Switching node. Connect the external power inductor between SW and the regulator output. Internally driven by the high-side and low-side power MOSFETs (RDS(on) ~37mΩ HS / ~25mΩ LS).
3 VIN power_in Supply input, 2.5V to 5.5V. Bypass with a 22µF ceramic capacitor to GND placed close to the pin. Absolute maximum 7V.
4 EN input Enable input. Drive high (rising threshold typ 1.2V, falling 0.4V) to enable the converter; drive low to shut down (IQ <1µA). For automatic start-up, tie EN to VIN through a pull-up resistor. Absolute maximum 7V.
5 FB input Feedback input to the internal error comparator. Connect an external resistor divider from VOUT to FB and GND to set the output voltage: VOUT = 0.6V × (1 + R1/R2). Internal reference 0.6V (±1%); R2 should be 1kΩ-70kΩ.
6 OUT input Output sense/feed-forward pin. Connect to VOUT (the regulated output rail) or leave not connected. Used internally by the Adaptive COT control loop.

  • ETA3458FSG

CAD (KiCad official)

  • Symbol: ETA3458FSG
  • Footprint: Package_TO_SOT_SMD:SOT-563
  • 3D model: SOT-563 (KiCad packages3D, STEP)
  • 3D model files: eta3458fsg-etched.step / eta3458fsg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); eta3458fsg.step / eta3458fsg.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
eta3458fsg.step 448 KB You want the bare part, or you mark your own boards.
eta3458fsg-etched.step 2.2 MB You want the part with ETA3458FSG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 464 faces against 54 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.
