| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NUMBER | ||
| FB | 1 | I | Voltage feedback. Connect to the center tape of a resistor divider to program the output voltage. |
| COMP | 2 | O | Output of the internal error amplifier, the loop compensation network should be connected between this pin and the AGND pin. |
| PGND | 3 | PWR | Power ground of the IC. It is connected to the source of the low-side MOSFET. |
| SW | 4,9 | PWR | The switching node pin of the converter. It is connected to the drain of the internal low-side power MOSFET and the source of the internal high-side power MOSFET. |
| VOUT | 5 | PWR | Boost converter output |
| EN | 6 | I | Enable logic input. Logic high level enables the device. Logic low level disables the device and turns it into shutdown mode. |
| VIN | 7 | I | IC power supply input |
| BST | 8 | O | Power supply for high-side MOSFET gate driver. A ceramic capacitor of 0.1 µF must be connected between this pin and the SW pin. |
| AGND | 10 | - | Signal ground of the IC |
| VCC | 11 | O | Output of the internal regulator. A ceramic capacitor of more than 1.0 µF is required between this pin and ground. |
