TMI3252SH from TMI, in a SOT-23-6. 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 | BS | passive | Bootstrap pin. A capacitor (typ. 0.1µF) is connected between LX and BS to form a floating supply for the high-side switch driver. |
| 2 | GND | power_in | Ground pin. Power and signal ground return for the device. |
| 3 | FB | input | Output voltage feedback input. Connect to the center point of the external resistor divider; internal reference VREF is 0.6V. |
| 4 | EN | input | Enable input. Drive logic-high (rising threshold 1.1V typ) to enable the IC; drive logic-low (falling threshold 0.94V typ) to enter micro-power shutdown. Do not float. Absolute max 20V. |
| 5 | IN | power_in | Power supply input pin. Operating input range 4.5V to 18V; absolute max 20V. Bypass with a low-ESR ceramic capacitor to GND. |
| 6 | LX | power_out | Switching node. Connects to the external inductor and to the bootstrap capacitor. Rated -0.3V to 20V DC (-4.5V to 22V <10ns transient). Delivers up to 2A output current. |

Two STEP files. Same geometry, different body top:

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 456 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.
