Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VOUT | input | Output voltage feedback pin for the buck converter, with the output range stated as 3 V to 12 V; C5 should be placed close to this pin. |
| 2 | VIN | power_in | Input voltage pin with a recommended range of 7.1 V to 32 V (absolute maximum -0.3 V to 40 V), and the input filter capacitor must be placed close to the IC. |
| 3 | SW | output | DC-DC switching node that connects to the inductor; LX voltage is limited to -0.3 V to VIN+0.3 V, and the R1/C6 RC snubber should be placed close to this pin. |
| 4 | BST | passive | Bootstrap pin that provides the high-side gate drive voltage; the bootstrap capacitor must be placed right next to the BST and SW pins, and the datasheet gives no separate voltage limit for this pin. |
| 5 | DM | bidirectional | USB fast-charge identification signal DM, with an absolute maximum of -0.3 V to 6 V and DP/DM overvoltage protection that trips at 4.5 V typical. |
| 6 | DP | bidirectional | USB fast-charge identification signal DP, with an absolute maximum of -0.3 V to 6 V and DP/DM overvoltage protection that trips at 4.5 V typical. |
| 7 | CC1 | bidirectional | Type-C detection pin CC1, with an absolute maximum of -0.3 V to 30 V and a CC overvoltage protection threshold of 6.0 V typical. |
| 8 | CC2 | bidirectional | Type-C detection pin CC2, with an absolute maximum of -0.3 V to 30 V and a CC overvoltage protection threshold of 6.0 V typical. |
| 9 | GND | power_in | Exposed pad (EPAD) that serves as both power and thermal ground and must make good contact with the PCB ground. |
