LMR12010XMK
Texas Instruments · DC-DC Converters · SOT-23-6
LMR12010XMK from Texas Instruments, in a SOT-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 | power_in | Boost voltage that drives the internal NMOS control switch, with a bootstrap capacitor connected between the BOOST and SW pins. |
| 2 | GND | power_in | Signal and power ground; the bottom resistor of the feedback network must be placed as close as possible to this pin for accurate regulation. |
| 3 | FB | input | Feedback pin, connected to the external resistor divider to set the output voltage. |
| 4 | EN | input | Enable control input where logic high enables operation; do not allow this pin to float or be greater than VIN + 0.3V. |
| 5 | VIN | power_in | Input supply voltage, with a bypass capacitor connected to this pin. |
| 6 | SW | output | Output switch that connects to the inductor, catch diode, and bootstrap capacitor. |
