Pin Functions
| PIN(1) | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NUMBER | ||
| PGND | 1 | Power ground | |
| VIN | 2 | I | Supply voltage |
| EN | 3 | I | Enable input (High = enabled, Low = disabled) |
| AGND | 4 | Analog ground | |
| FB | 5 | I | Voltage feedback of adjustable version. Connect resistive voltage divider to this pin. It is recommended to connect FB to AGND on fixed output voltage versions for improved thermal performance. |
| VOS | 6 | I | Output voltage sense pin and connection for the control loop circuitry. |
| SW | 7 | O | Switch node, which is connected to the internal MOSFET switches. Connect inductor between SW and output capacitor. |
| PG | 8 | O | Output power good (High = VOUT ready, Low = VOUT below nominal regulation) ; open drain (requires pull-up resistor; goes high impedance, when device is switched off) |
| Exposed Thermal Pad | Must be connected to AGND. Must be soldered to achieve appropriate power dissipation and mechanical reliability. | ||
