## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | power_out | Switched-node connection, connected to the source of the internal high-side MOSFET. |
| 2 | SW | power_out | Switched-node connection, connected to the source of the internal high-side MOSFET. |
| 3 | PVIN | power_in | Main power supply input connected to the drain of the internal high-side MOSFET; supply range is 3.8V ≤ VIN ≤ 14V per the absolute maximum ratings. |
| 4 | PVIN | power_in | Main power supply input connected to the drain of the internal high-side MOSFET; supply range is 3.8V ≤ VIN ≤ 14V per the absolute maximum ratings. |
| 5 | PVIN | power_in | Main power supply input connected to the drain of the internal high-side MOSFET; supply range is 3.8V ≤ VIN ≤ 14V per the absolute maximum ratings. |
| 6 | VCB | passive | Bootstrap capacitor connection for high-side gate drive; VCB voltage is rated 7V maximum (Note 7). |
| 7 | AVIN | power_in | Input voltage for control and drive circuits; rated 4.0V ≤ VIN ≤ 14V per the absolute maximum ratings. |
| 8 | SD(SS) | input | Shutdown and soft-start control: pulling this pin below 0.3V shuts off the regulator, a capacitor to ground sets the control ramp of the input current, and it must not be driven by an external source. |
| 9 | FB | input | Output voltage feedback input connected to the output voltage; absolute maximum pin voltage range is -0.4V ≤ VFB ≤ 5V. |
| 10 | COMP | passive | Compensation network connection to the output of the voltage error amplifier; absolute maximum voltage is 2.5V. |
| 11 | LDELAY | passive | A capacitor from this pin to ground sets the delay from the output reaching 80% of nominal to enabling undervoltage latch protection; absolute maximum voltage is 2.5V. |
| 12 | LDR | output | Low-side FET gate drive output for synchronous operation; absolute maximum voltage is 5V. |
| 13 | GND | power_in | Power ground. |
| 14 | PVIN | power_in | Main power supply input connected to the drain of the internal high-side MOSFET; supply range is 3.8V ≤ VIN ≤ 14V per the absolute maximum ratings. |
| 15 | PVIN | power_in | Main power supply input connected to the drain of the internal high-side MOSFET; supply range is 3.8V ≤ VIN ≤ 14V per the absolute maximum ratings. |
| 16 | PVIN | power_in | Main power supply input connected to the drain of the internal high-side MOSFET; supply range is 3.8V ≤ VIN ≤ 14V per the absolute maximum ratings. |
