**Texas Instruments** · DC-DC Converters · TSOT-23-6

LMR12007YMKX 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 | output | Boost voltage driver for internal NMOS gate with bootstrap capacitor between BOOST and SW pins; operating voltage (VBOOST - VSW) 1.6 V to 5.5 V. |
| 2 | GND | power_in | Signal and power ground pin; place feedback network return close to this pin for accurate regulation. |
| 3 | FB | input | Feedback input for external resistor divider to set output voltage; absolute maximum voltage -0.5 V to 3.0 V. |
| 4 | EN | input | Logic enable control input; high enables operation with 0.4 V shutdown threshold and 1.8 V enable threshold; do not exceed VIN + 0.3 V. |
| 5 | VIN | power_in | Input supply voltage with operating range 3.0 V to 18.0 V and absolute maximum -0.5 V to 22 V; bypass capacitor connection required. |
| 6 | SW | output | Output switch node connecting to inductor and catch diode with operating voltage -0.5 V to 18 V and absolute maximum -0.5 V to 22 V. |
