XC9133B02AMR-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 that connects to the anode of the Schottky barrier diode and the inductor; the absolute maximum Lx pin voltage is 22.0V and the Lx overvoltage limit is 19V (TYP.). |
| 2 | VSS | power_in | Ground pin; the absolute maximum rating for the VIN, FB and CE pins is referenced to VSS (VSS - 0.3V to 7.0V for those pins). |
| 3 | FB | input | Voltage feedback pin with a 0.2V reference (0.19V to 0.21V); the LED-current set resistor RLED connects here with RLED = 0.2 / ILED, and the absolute maximum FB pin voltage is 7.0V. |
| 4 | CE | input | Chip enable pin where the IC is enabled above 0.65V and disabled below 0.2V, and which accepts PWM dimming up to 10kHz; the absolute maximum CE pin voltage is 7.0V. |
| 5 | VIN | power_in | Power input with an operating range of 2.5V to 6.0V and an absolute maximum rating of 7.0V; an inductor and input bypass capacitor CIN (4.7µF) are connected here. |
