LP6470B6F from LOWPOWER, 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 | GND | power_in | Ground reference pin for the converter. |
| 2 | SW | output | Switch-mode connection to the inductor, tied to the drains of the internal main and synchronous power MOSFETs. |
| 3 | VIN | power_in | Voltage supply input, rated 3.5V to 16V with undervoltage lockout at 3.3V and overvoltage protection at 18V. |
| 4 | FB | input | Feedback input that connects to the center point of the external resistor divider, with a normal voltage of 0.8V. |
| 5 | EN | input | Enable control input: drive above 1.8V to turn the channel on and below 0.4V to turn it off. |
| 6 | BS | passive | High-side gate drive boost input; connect a 0.01uF or greater capacitor from SW to BS to power the high-side switch. |
