Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Power supply input pin, operating range 2.5V to 5.5V (absolute maximum -0.3 to 6.0V). |
| 2 | VSS | power_in | Ground pin. |
| 3 | CE | input | Enable input; logic high (1.4V to 5.5V) turns the converter on and logic low (VSS to 0.3V) turns it off. |
| 4 | VOUT | input | Output voltage sense pin (fixed 3.3V output, absolute maximum -0.3 to 4.0V) with internal fast discharge when the device is disabled. |
| 5 | Lx | output | Switching node pin connecting to the inductor, absolute maximum -0.3 to 6.2V. |
