Pin Functions
| NAME | SOT23-5 | SOT23-6 | SOT563-6 | I/O/PWR | DESCRIPTION |
|---|---|---|---|---|---|
| EN | 1 | 1 | 5 | I | Device enable logic input. Logic high enables the device, logic low disables the device and turns it into shutdown. Do not leave floating. |
| GND | 2 | 2 | 2 | PWR | Ground pin. |
| SW | 3 | 3 | 4 | PWR | Switch pin connected to the internal FET switches and inductor terminal. Connect the inductor of the output filter to this pin. |
| VIN | 4 | 4 | 3 | PWR | Power supply voltage input. |
| PG | - | 5 | 6 | O | Power good open drain output pin for TLV62569P. The pull-up resistor should not be connected to any voltage higher than 5.5V. If it's not used, leave the pin floating. |
| FB | 5 | 6 | 1 | I | Feedback pin for the internal control loop. Connect this pin to an external feedback divider. |
| NC | - | - | 6 | O | No connection pin for TLV62569DRL. The pin can be connected to the output or the ground. Or leave it floating. |
