Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | power_out | Power switch output; drain of the internal 80 mΩ N-channel power MOSFET. Connect the boost inductor and Schottky rectifier here. SW can swing between GND and 22V (absolute max). |
| 2 | GND | power_in | Device ground return. Should be tied to a solid ground plane for heat sinking and noise immunity. |
| 3 | FB | input | Feedback input to the internal error amplifier. Regulates to VREF = 0.6V (typ). Connect an external R1/R2 resistor divider from VOUT to set the output voltage: VOUT = 0.6V × (1 + R1/R2). Input bias current ≈ -10 nA typ. |
| 4 | EN | input | Regulator on/off control input. Drive high (VIH ≥ 1.5V) to enable the converter; low (VIL ≤ 0.6V) to shut it down (IQ ≈ 0.1 µA). Tie to VIN for automatic startup. Absolute max 18V. |
| 5 | VIN | power_in | Input supply pin, 2.2V to 16V operating range (18V abs max). Must be locally bypassed with a low-ESR ceramic capacitor (22 µF recommended). Feeds the internal UVLO (2.2V typ) and control circuitry. |
| 6 | OC | input | Adjustable over-current programming pin. A resistor from OC to GND (19 kΩ-96 kΩ) sets peak switch current from 2.5A down to 0.5A per IOCP = 48000 / R. Leave floating to use the internal 2.5A default limit. Keep trace short. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 402 faces against 117 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
