TPS22945DCKR

Texas Instruments · AC-DC Controllers and Regulators · SC-70-5

TPS22945DCKR from Texas Instruments, in a SC-70-5. 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 VOUT power_out Switch output. Connects to the load through the internal P-channel MOSFET (rON ≈ 0.4 Ω at VIN = 5.5 V). Place a ceramic bypass capacitor between VOUT and GND.
2 GND power_in Device ground reference.
3 OC output Over-current output flag. Active-LOW, open-drain output that asserts during over-current, undervoltage, or over-temperature conditions. VOL ≤ 0.2 V at ISINK = 10 mA; requires an external pull-up resistor.
4 ON input Switch control input (active HIGH on TPS22945). 1.8 V compatible logic thresholds (VIH ≥ 1.1 V at VIN = 1.8 V; VIH ≥ 1.7 V at VIN = 5.5 V). Do not leave floating.
5 VIN power_in Switch input supply, 1.62 V to 5.5 V. Source terminal of the internal P-channel MOSFET. Place a ceramic bypass capacitor between VIN and GND.

Two STEP files. Same geometry, different body top:

File Size Use it when
tps22945dckr.step 87 KB You want the bare part, or you mark your own boards.
tps22945dckr-etched.step 2.4 MB You want the part with TPS22945DCKR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 577 faces against 102 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: Texas Instruments datasheet (25 pp, sha256 b5668708867c75e7, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
