| 4 | SD | input | Active-low shutdown input; 200-kΩ internal pull-down resistor to GND |
| 5 | GND | power_in | Ground; must be connected externally to pins 5, 6, and DAP |
| 6 | GND | power_in | Ground; must be connected externally |
| 7 | CAP- | passive | Flying capacitor negative terminal |
| 8 | VIN | power_in | Input voltage supply 2.7V to 5.6V; must be connected externally |
| 9 | VIN | power_in | Input voltage supply 2.7V to 5.6V; must be connected externally |
| 10 | CAP+ | passive | Flying capacitor positive terminal |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
