XC9119D10AMR-G from Torex Semicon, in a SOT-25-5. 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 | Lx | output | Switch pin: connect the anode of the Schottky barrier diode and the inductor here; the Lx pin voltage must not exceed 20.0V operating (22.0V absolute maximum). |
| 2 | VSS | power_in | Ground pin; absolute maximum rating range is VSS - 0.3V to 7.0V for VDD, FB and CE pins referenced to it. |
| 3 | FB | input | Voltage feedback pin with a 1.0V (TYP.) reference, where output voltage is set by RFB1 and RFB2 (sum of the two should be 1MΩ or less); absolute maximum is VSS - 0.3V to 7.0V. |
| 4 | CE/SS | input | Chip enable / soft-start pin: high level (CE 'H', minimum 0.65V) starts operation and low level (CE 'L', maximum 0.20V) shuts down; absolute maximum is VSS - 0.3V to 7.0V. |
| 5 | VDD | power_in | Power supply input operating from 2.5V to 6.0V, which should be decoupled with an input bypass capacitor (CIN); absolute maximum is VSS - 0.3V to 7.0V. |
