LM2734YMK 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 with bootstrap capacitor connected between BOOST and SW pins. |
| 2 | GND | power_in | Signal and power ground pin for accurate regulation of feedback network. |
| 3 | FB | input | Feedback pin connected to external resistor divider to set output voltage. |
| 4 | EN | input | Enable control input requiring logic high for operation; voltage must not exceed VIN + 0.3 V. |
| 5 | VIN | power_in | Input supply voltage pin in range 3 V to 20 V with bypass capacitor required. |
| 6 | SW | output | Output switch pin connected to inductor, catch diode, and bootstrap capacitor. |
