Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Enable control: pull high to turn on and do not leave it floating. |
| 2 | GND | power_in | Ground pin. |
| 3 | LX | output | Inductor pin, connected to the switching node of the inductor. |
| 4 | IN | power_in | Input pin, decoupled to the GND pin with at least a 10µF ceramic capacitor. |
| 5 | FB | input | Output feedback pin, connected to the center point of the output resistor divider to program the output voltage VOUT=0.6×(1+RH/RL). |
