Texas Instruments · DC-DC Converters · SOT-23-5
LM27313XQMFX from Texas Instruments, in a SOT-23-5. 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 | SW | output | Drain of the internal FET switch with maximum voltage rating of 30 V. |
| 2 | GND | power_in | Analog and power ground. |
| 3 | FB | input | Feedback point that connects to external resistive divider to set VOUT with voltage range −0.4 to 6 V. |
| 4 | SHDN | input | Shutdown control input with recommended voltage range 0 to VIN; connect to VIN if this feature is not used. |
| 5 | VIN | power_in | Analog and power input with recommended operating voltage range 2.7 to 14 V. |
