| EN | 2 | 9 | I | This pin is the enable pin of the device. Connect to logic low to disable the device. Pull high to enable the device. Do not leave this pin unconnected. |
| FB | 7 | 3 | I | Voltage feedback input. Connect the output voltage resistor divider to this pin. |
| GND | 6, 10, 13, 14 | 2, 6, 12 | Ground pin | |
| MODE/SYNC | 4 | 11 | I | The device runs in PFM/PWM mode when this pin is pulled low. When the pin is pulled high, the device runs in forced PWM mode. Do not leave this pin unconnected. The MODE/SYNC pin can also be used to synchronize the device to an external frequency. See Section 9.3.2. |
| COMP/FSET | 9 | 5 | I | Device compensation and frequency set input. A resistor from this pin to GND defines the compensation of the control loop as well as the switching frequency if not externally synchronized. The switching frequency is set to 2.25 MHz if the pin is tied to GND or VIN. See Table 8-1. Do not leave this pin unconnected. |
| PG | 3 | 10 | O | Open-drain power-good output with window comparator. This pin is pulled to GND while VOUT is outside the power-good threshold. This pin can be left open or tied to GND if not used. A pullup resistor can be connected to any voltage not larger than VIN. |
| SS/TR | 8 | 4 | I | Soft-start, tracking pin. A capacitor connected from this pin to GND defines the output voltage rise time. The pin can also be used as an input for tracking and sequencing - see Voltage Tracking. |
| VOUT | 5 | 1 | Output voltage pin. This pin is internally connected to the integrated inductor. | |
| VIN | 1, 11, 12 | 8, 13 | Power supply input. Connect the input capacitor as close as possible between the VIN and GND pins. | |
| SW | — | 7 | O | This pin is the switch pin of the converter. This pin is connected to the internal power MOSFET and the inductor. Leave this pin unconnected for best EMI performance. |
