Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VOUT_LDO0 | power_out | LDO0 output. If the LDO0 is not used, leave the pin floating. |+| 2 | FB_B0 | passive | Output voltage feedback (positive) for Buck 0. |+| 3 | FB_B1 | passive | Output voltage feedback (positive) for Buck 1. |+| 4 | AGND | power_in | Ground. |+| 5 | VANA | power_in | Supply voltage for analog and digital blocks. Must be connected to same node with VIN_Bx. |+| 6 | EN | input | Programmable enable signal for regulators and GPOs. If the pin is not used, leave the pin floating. |+| 7 | VOUT_LDO1 | power_out | LDO1 output. If LDO1 is not used, leave the pin floating. |+| 8 | VIN_LDO1 | power_in | Power input for LDO1. If LDO1 is not used, connect the pin to VANA. |+| 9 | nINT | output | Open-drain interrupt output. Active LOW. If the pin is not used, connect the pin to ground. |+| 10 | CLKIN | bidirectional | External clock input. Alternative function is general-purpose digital output (GPO2). If the pin is not used, leave the pin floating. |+| 11 | VIN_B1 | power_in | Input for Buck 1. The separate power pins VIN_Bx are not connected together internally - VIN_Bx pins must be connected together in the application and be locally bypassed. |+| 12 | VIN_B1 | power_in | Input for Buck 1. The separate power pins VIN_Bx are not connected together internally - VIN_Bx pins must be connected together in the application and be locally bypassed. |+| 13 | SW_B1 | power_out | Buck 1 switch node. If the Buck 1 is not used, leave the pin floating. |+| 14 | SW_B1 | power_out | Buck 1 switch node.

Connect a pullup resistor. If the I2C interface is not used, connect the pin to Ground. |+| 18 | SDA | bidirectional | Serial interface data input and output for I2C access. Connect a pullup resistor. If the I2C interface is not used, connect the pin to Ground. |+| 19 | SGND | power_in | Ground. |+| 20 | PGND_B0 | power_in | Power ground for Buck 0. |+| 21 | PGND_B0 | power_in | Power ground for Buck 0. |+| 22 | SW_B0 | power_out | Buck 0 switch node.
