XT1861B332MR-G
NATLINEAR · DC-DC Converters · SOT-23-3L
XT1861B332MR-G from NATLINEAR, in a SOT-23-3L. 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 | GND | power_in | Ground / reference return (接地端). Connect to system ground. |
| 2 | LX | passive | Switch node (开关). Connects to the external boost inductor between VIN and the internal power switch / synchronous rectifier. Rated 1000 mA maximum switch current, 6.5 V absolute maximum. |
| 3 | VOUT | power_out | Regulated boost output (输出端), factory-set to 3.3 V ±2.5% (suffix '33'). Also serves as the IC supply once the output is above the input. Bypass with a 22 µF ceramic capacitor to GND. 6.5 V absolute maximum. |
