| PIN | I/O | DESCRIPTION | ||
|---|---|---|---|---|
| NAME | NO. | |||
| HTSSOP | VQFN | |||
| BASE | 3 | 6 | O | Base drive output for the external transistor |
| C1+ | 16 | 19 | — | Positive terminal of the charge pump flying capacitor |
| C1– | 17 | 20 | — | Negative terminal of the charge pump flying capacitor |
| C2+ | 14 | 17 | — | Positive terminal for the charge pump flying capacitor. If the device runs in voltage doubler mode, this pin must be left open. |
| C2–/MODE | 15 | 18 | — | Negative terminal of the charge pump flying capacitor and charge pump MODE pin. If the flying capacitor is connected to this pin, the converter operates in a voltage tripler mode. If the charge pump must operate in a voltage doubler mode, the flying capacitor is removed and the C2-/MODE pin must be connected to GND. |
| COMP | 22 | 1 | — | Compensation pin for the main boost converter. A small capacitor is connected to this pin. |
| DRV | 18 | 21 | O | External charge pump driver |
| EN | 24 | 3 | I | Enable pin of the device. This pin must be terminated and not be left floating. A logic high enables the device and a logic low shuts down the device. |
| ENR | 23 | 2 | I | Enable pin of the linear regulator controller. This pin must be terminated and not be left floating. Logic high enables the regulator and a logic low puts the regulator in shutdown. |
| FB1 | 1 | 4 | I | Feedback pin of the boost converter |
| FB2 | 21 | 24 | I | Feedback pin of negative charge pump |
| FB3 | 12 | 15 | I | Feedback pin of positive charge pump |
| FB4 | 2 | 5 | I | Feedback pin of the linear regulator controller. The linear regulator controller is set to a fixed output voltage of 3.3 V or 3 V depending on the version. |
| GND | 11, 19 | 14, 22 | — | Ground |
| OUT3 | 13 | 16 | O | Positive charge pump output |
| PG | 10 | 13 | O | Open-drain output indicating when all outputs VO1, VO2, VO3 are within 10% of their nominal output voltage. The output goes low when one of the outputs falls below 10% of their nominal output voltage. |
| PGND | 7, 8 | 10, 11 | — | Power ground |
| PowerPAD / Thermal Die | — | — | — | The PowerPAD or exposed thermal die must be connected to power ground pins (PGND) |
| REF | 20 | 23 | O | Internal reference output typically 1.23 V |
| SUP | 9 | 12 | I | Supply pin of the positive, negative charge pump, boost converter, and gate drive circuit. This pin must be connected to the output of the main boost converter and cannot be connected to any other voltage source. For performance reasons, TI does not recommend connecting a bypass capacitor directly to this pin. |
| SW | 5, 6 | 8, 9 | I | Switch pin of the boost converter |
| VIN | 4 | 7 | I | Input voltage pin of the device. |
