UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
| PIN | TYPE | DESCRIPTION | |
|---|---|---|---|
| NO. | NAME | ||
| 1 | SW | O | This is the switch pin and is connected to the internal MOSFET switches. Connect the external inductor between this terminal and the output capacitor. |
| 2 | MODE | I | Pulling this pin to high forces the device to operate in fixed-frequency PWM mode. Pulling this pin to low enables the Power Save Mode with automatic transition from PFM mode to fixed-frequency PWM mode. |
| 3 | FB | I | Feedback Pin for the internal regulation loop. Connect the external resistor divider to this pin. In case of fixed output voltage option, connect this pin directly to the output capacitor |
| 4 | EN | I | This is the enable pin of the device. Pulling this pin to low forces the device into shutdown mode. Pulling this pin to high enables the device. This pin must be terminated. |
| 5 | VIN | PWR | VIN power supply pin. |
| 6 | GND | GND | GND supply pin |
| — | PowerPAD | GND | GND pin must be electrically connected to the exposed pad on the printed-circuit board for proper operation. |
