LMR14006YDDCR from Texas Instruments, in a TSOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CB | passive | Bootstrap capacitor connection between this pin and SW pin; stores and supplies 4V to 6V bias voltage for internal high-side MOSFET gate drive. |
| 2 | GND | power_in | Ground connection; signal and power return path for internal circuits and external components. |
| 3 | FB | input | Feedback input for output voltage regulation; set VOUT = 0.765V × (1 + R1/R2) using external resistor divider with input range 0V to 5.5V. |
| 4 | /SHDN | input | Active-low enable input; pull below 1.25V typical rising threshold (1.05V to 1.38V range) to disable or leave floating to enable; high voltage tolerant to 40V. |
| 5 | VIN | power_in | Power supply input; 4V to 40V operating range supplies internal circuits and serves as drain connection for internal high-side MOSFET. |
| 6 | SW | output | Switch node output; connects to external inductor, Schottky diode, and bootstrap capacitor; drives up to 600mA peak switching current with voltage swing of -1V to 45V. |
