Pin Functions
| PIN | I/O | DESCRIPTION | |||
|---|---|---|---|---|---|
| NAME | SOT-23 | WSON | MSOP-
PowerPAD |
||
| AGND | — | 5 | 6 | PWR | Signal ground pin. Place the bottom resistor of the feedback network as close as possible to this pin and pin 4.
For MSOP-PowerPAD, place the bottom resistor of the feedback network as close as possible to this pin and pin 5 |
| EN | 4 | 3 | 4 | I | Shutdown control input. Logic high enables operation. Do not allow this pin to float or be greater than VIN + 0.3 V. |
| FB | 3 | 4 | 5 | I | Feedback pin. Connect FB to external resistor-divider to set output voltage. |
| GND | 2 | DAP | DAP | PWR | Signal and power ground pin. Place the bottom resistor of the feedback network as close as possible to this pin.
For WSON, connect to pin 1 and pin 5 on top layer. Place 4-6 vias from DAP to bottom layer GND plane. |
| NC | — | — | 1, 8 | — | No Connect |
| PGND | — | 1 | 2 | PWR | Power ground pin. Place PGND and output capacitor GND close together. |
| SW | 1 | 6 | 7 | O | Output switch. Connect to the inductor, output diode. |
| VIN | 5 | 2 | 3 | PWR | Supply voltage for power stage, and input supply voltage. |
