TPS61222DCKR

Texas Instruments · DC-DC Converters · SC-70-6(SOT-363)

TPS61222DCKR from Texas Instruments, in a SC-70-6(SOT-363). 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 Boost converter input voltage. Operating range 0.7 V to 5.5 V; absolute maximum 7.5 V. Bypass with a low-ESR ceramic capacitor (typ. 10 uF) close to the pin.
2 FB input Voltage feedback pin. On the adjustable TPS61220 it connects to an external resistor divider from VOUT (VFB typ. 500 mV). On fixed-output versions (TPS61221/TPS61222) this pin must be tied directly to VOUT.
3 GND power_in Control/logic and power ground. Common return for input and output capacitors.
4 VOUT power_out Boost converter regulated output. For TPS61222 this is a fixed 5.0 V (4.82 V to 5.13 V) output; internal synchronous rectifier switch connects L to VOUT. Bypass with a low-ESR ceramic capacitor (typ. 10 uF).
5 L passive Switching node / connection for the boost inductor (typ. 4.7 uH). Connects between the external inductor from VIN and the internal main and rectifier MOSFETs. Absolute maximum 7.5 V.
6 EN input Enable input. Logic high (>= 0.8VIN, or >= 1.2 V when VIN > 1.5 V) enables the converter; logic low (<= 0.2VIN, or <= 0.4 V when VIN > 1.5 V) disables and enters pass-through mode. Must be actively driven high or low, do not leave floating.

Ordering variants

CAD (KiCad official)

  • Symbol: TPS61222DCKR
  • Footprint: Package_TO_SOT_SMD:SOT-363_SC-70-6
  • 3D model: SC-70-6(SOT-363) (KiCad packages3D, STEP)
  • 3D model files: tps61222dckr-etched.step / tps61222dckr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps61222dckr.step / tps61222dckr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tps61222dckr.step 99 KB You want the bare part, or you mark your own boards.
tps61222dckr-etched.step 2.4 MB You want the part with TPS61222DCKR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 581 faces against 117 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.
