PIN | TYPE(1) | DESCRIPTION | |
---|---|---|---|
NO. | NAME | ||
1 | FB_B2 | A | Output voltage feedback (positive) for the BUCK2 converter. |
2 | EN3 | D/I/O | Programmable enable signal for the buck regulators (can be also configured to select between two buck output-voltage levels). This pin functions alternatively as GPIO3. |
3 | CLKIN | D/I | External clock input. Connect this pin to ground if the external clock is not used. |
4, 17, Thermal Pad | AGND | G | Ground |
5 | SCL | D/I | Serial interface clock input for I2C access. Connect this pin to a pullup resistor. |
6 | SDA | D/I/O | Serial interface data input and output for I2C access. Connect this pin to a pullup resistor. |
7 | EN1 | D/I/O | Programmable enable signal for the buck regulators (can be also configured to select between two buck output voltage levels). This pin functions alternatively as GPIO1. |
8 | FB_B0 | A | Output voltage feedback (positive) for the BUCK0 converter. |
9 | VIN_B0 | P | Input for the BUCK0 converter. The separate power pins, VIN_Bx, are not connected together internally. The VIN_Bx pins must be connected together in the application and be locally bypassed. |
10 | SW_B0 | A | BUCK0 switch node |
11 | PGND_B01 | G | Power ground for the BUCK0 and BUCK1 converters |
12 | SW_B1 | A | BUCK1 switch node |
13 | VIN_B1 | P | Input for the BUCK1 converter. The separate power pins, VIN_Bx, are not connected together internally. The VIN_Bx pins must be connected together in the application and be locally bypassed. |
14 | FB_B1 | A | Output voltage feedback (positive) for the BUCK1 converter. This pin functions alternatively as the output ground feedback (negative) for the BUCK0 converter. |
15 | EN2 | D/I/O | Programmable enable signal for the buck regulators (can be also configured to select between two buck output voltage levels). This pin functions alternatively as GPIO2. |
16 | PGOOD | D/O | Power-good indication signal |
18 | VANA | P | Supply voltage for the analog and digital blocks. This pin must be connected to the same node as VIN_Bx. |
19 | nINT | D/O | Open-drain interrupt output. This pin is active low. |
20 | NRST | D/I | Reset signal for the device |
21 | FB_B3 | A | Output voltage feedback (positive) for the BUCK3 converter. This pin functions alternatively as the output ground feedback (negative) for the BUCK2 converter. |
22 | VIN_B3 | P | Input for the BUCK3 converter. The separate power pins, VIN_Bx, are not connected together internally. The VIN_Bx pins must be connected together in the application and be locally bypassed. |
23 | SW_B3 | A | BUCK3 switch node |
24 | PGND_B23 | G | Power ground for the BUCK2 and BUCK3 converters |
25 | SW_B2 | A | BUCK2 switch node |
26 | VIN_B2 | P | Input for the BUCK2 converter. The separate power pins, VIN_Bx, are not connected together internally. The VIN_Bx pins must be connected together in the application and be locally bypassed. |
