PRODUCTION DATA.
| PIN | DESCRIPTION | |
|---|---|---|
| NO. | NAME | |
| 1 | BOOST | Boost voltage that drives the internal NMOS control switch. A bootstrap capacitor is connected between the BOOST and SW pins. |
| 2 | GND | Signal and Power ground pin. Place the bottom resistor of the feedback network as close as possible to this pin for accurate regulation. |
| 3 | FB | Feedback pin. Connect FB to the external resistor divider to set output voltage. |
| 4 | EN | Enable control input. Logic high enables operation. Do not allow this pin to float or be greater than VIN + 0.3V. |
| 5 | VIN | Input supply voltage. Connect a bypass capacitor to this pin. |
| 6 | SW | Output switch. Connects to the inductor, catch diode, and bootstrap capacitor. |
