LMR12015XSD from Texas Instruments, in a WSON-10-EP(3x3). 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 | Output switch that connects to the inductor, catch diode, and bootstrap capacitor. |
| 2 | SW | output | Output switch that connects to the inductor, catch diode, and bootstrap capacitor (second SW pin, same net as pin 1). |
| 3 | BOOST | power_out | Boost voltage that drives the internal NMOS control switch, with a bootstrap capacitor connected between BOOST and SW. |
| 4 | EN | input | Enable control input where logic high enables operation; do not allow this pin to float or to be greater than VIN + 0.3 V. |
| 5 | SYNC | input | Frequency synchronization input that is driven by an external clock or pulse train, or grounded to use the internal clock. |
| 6 | FB | input | Feedback pin that connects to the external resistor divider to set the output voltage. |
| 7 | GND | power_in | Signal and power ground; place the bottom resistor of the feedback network as close as possible to this pin for accurate regulation. |
| 8 | AVIN | power_in | Supply voltage for the control circuitry, rated 3 V to 20 V in the recommended operating ratings. |
| 9 | PVIN | power_in | Supply voltage for the output power stage; connect a bypass capacitor to this pin. |
| 10 | PVIN | power_in | Supply voltage for the output power stage; connect a bypass capacitor to this pin (second PVIN pin, same net as pin 9). |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
