LP6222SPF from LOWPOWER, in a ESOP-8. 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 | Ground return. Connect to system ground plane; tie together with pins 5 and the exposed pad (pin 9) for low-impedance return of the switching current. |
| 2 | FB | input | Regulation feedback input. Connect an external resistive voltage divider from VOUT to FB to program the output voltage; the internal reference is 0.6 V so VOUT = (R1/R2 + 1) x 0.6 V. |
| 3 | LX | power_out | Switching node. Connect to the boost inductor and the anode of the Schottky rectifier. Rated to 12 V max relative to GND; keep trace short to minimize EMI. Tied to pin 4 internally to share switching current. |
| 4 | LX | power_out | Switching node (paralleled with pin 3). Both LX pins should be tied together at the inductor for the full 4.8 A switch current rating. |
| 5 | GND | power_in | Ground return (paralleled with pin 1 and the exposed thermal pad on pin 9). |
| 6 | ISET | input | Peak switch current programming input. A resistor R3 between ISET and GND (10 kΩ to 96 kΩ) sets the cycle-by-cycle current limit from 4.8 A down to 0.5 A per IOCP = 48000 / R3. Keep trace short; do not add capacitance on this pin. |
| 7 | VIN | power_in | Input supply. Operating range 2.5 V to 5.5 V (6 V absolute max). Bypass with a 22 μF low-ESR ceramic capacitor to GND placed close to the pin. |
| 8 | EN | input | Enable/shutdown control input. VEN > 1.4 V enables the regulator; VEN < 0.4 V forces low-current shutdown (<1 μA). Do not leave floating. |
| 9 | GND | power_in | Exposed thermal pad on the ESOP-8 underside. Must be soldered to the ground plane for thermal dissipation (θJA ≈ 50 °C/W); electrically tied to GND (pins 1 and 5). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 494 faces against 152 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.
