LMR16006YQDDCRQ1 from Texas Instruments, in a SOT-23-THIN-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 | CB | input | Switch FET gate bias voltage node; CB to SW voltage range -0.3V to 6V. |
| 2 | GND | power_in | Ground connection (0V reference). |
| 3 | FB | input | Feedback input for output voltage divider setting; operating voltage range 0V to 5.5V. |
| 4 | SHDN | input | Enable/disable input with high voltage tolerance and internal pull-up; pull below 1.25V to disable, float to enable; operating range 0V to 40V. |
| 5 | VIN | power_in | Power supply input for internal circuits and high-side MOSFET drain; operating voltage 4V to 40V with 65V transient tolerance. |
| 6 | SW | output | Switch node output to inductor, diode, and Cboot capacitor; voltage range -1V to 40V (or -2V to 60V for transients less than 30ns). |
