LM2734YMKX from Texas Instruments, in a TSOT-23-6. 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 | BOOST | input | Boost voltage that drives the internal NMOS control switch; a bootstrap capacitor is connected between the BOOST and SW pins. |
| 2 | GND | power_in | Signal and power ground pin; place the bottom resistor of the feedback network as close as possible to this pin for accurate regulation. |
| 3 | FB | input | Feedback pin; connect FB to the external resistor divider to set output voltage. |
| 4 | EN | input | Enable control input; logic high enables operation; do not allow this pin to float or exceed VIN + 0.3 V. |
| 5 | VIN | power_in | Input supply voltage; connect a bypass capacitor to this pin. |
| 6 | SW | output | Output switch; connects to the inductor, catch diode, and bootstrap capacitor. |
