TPS61045DRBR from Texas Instruments, in a VSON-8-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | L | output | Drain of internal input switch Q1 connected to the inductor. |
| 2 | VIN | power_in | Input supply pin with operating voltage range from 1.8 V to 6 V. |
| 3 | DO | output | Internal DAC output that programs the output voltage through the CTRL pin. |
| 4 | FB | input | Feedback input connected to the output voltage-feedback divider. |
| 5 | CTRL | input | Combined enable and digital output voltage programming input pin. |
| 6 | GND | power_in | Analog ground that must be directly connected to the PGND pin. |
| 7 | PGND | power_in | Power ground and exposed thermal pad connection point. |
| 8 | SW | output | Drain of internal main switch Q2 with 30 V absolute maximum voltage; connects to inductor and Schottky rectifier diode anode. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
