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 | GND | power_in | Device ground / power return. |+| 2 | LX | output | Switching node - drain of the internal power NMOS. Connect to the boost inductor and Schottky diode anode. Absolute maximum LX voltage 7 V, peak switch current up to 1000 mA (typical current limit 800 mA). |+| 3 | VOUT | power_in | Output-voltage sense / device supply pin. Connect to the regulated output rail (nominally 5.0 V for the '50' suffix) after the Schottky diode; the internal feedback divider senses this node.
