Table 5-1 Pin Functions
PIN I/O TYPE DESCRIPTION CONNECTION IF NOT USED
NO. NAME
1 SCL I Digital I2C interface serial clock (external pull up). VCCA
2 FB_B1 — Analog Output voltage feedback for BUCK1. GND
3 SDA I / O Digital I2C interface bidirectional serial data (external pull up). VCCA
4 AGND — Ground Ground. Ground
5 nRSTOUT O Digital Reset output. Floating
6 FB_B3 — Analog Output voltage feedback for BUCK3. Ground
7 ENABLE I Digital Programmable ENABLE signal. Not applicable
8 SW_B3 — Analog BUCK3 switch node. Floating
9 PVIN_B3 — Power Power input for BUCK3. The separate power pins PVIN_Bxx are not connected together internally – PVIN_Bxx and VCCA pins must be connected together in the application and be locally bypassed. PMIC input supply
10 PGND_B3 — Ground Power ground for BUCK3. Ground
11 VOUT_LDO_LS1/VMON1 — Power Output voltage of LDO_LS1 Floating
— Analog Alternative programmable function: Voltage monitoring input GND
12 PVIN_LDO_LS1 — Power Input voltage of LDO_LS1 VCCA
13 VOUT_LS2/VMON2/SYNCCLK — Power Output of Load Switch 2 GND
— Analog Alternative programmable function: Voltage monitoring input GND
I Digital Alternative programmable function: External clock input. GND
14 PVIN_LS2/nINT/GPIO — Power Input supply for Load Switch 2 Ground
O Digital Alternative programmable function: Interrupt output for System MCU Floating
I/O Digital Alternative programmable function (output): General purpose output. Alternative programmable function (input): I2C address selection through external pull -up / pull-down Floating
15 VOUT_VLDO — Power Internal LDO regulator filter node. LDO is used for internal purposes. -
16 AGND — Ground Ground. Ground
17 VCCA — Power Supply voltage for internal LDO. VCCA and PVIN_Bxx pins must be connected together in the application and be locally bypassed. System supply
18 FB_B2 — Analog Output voltage feedback for BUCK2. Ground
19 nERR/WD_DIS I Digital Primary function: System MCU Error Monitoring Input. Ground
I Digital Alternative programmable function: Watchdog Disable Input. Ground
20 SW_B2 — Analog BUCK2 switch node. Floating
21 PVIN_B2 — Power Power input for BUCK2. The separate power pins PVIN_Bxx are not connected together internally – PVIN_Bxx and VCCA pins must be connected together in the application and be locally bypassed. System supply
22 PGND_B12 — Ground Power ground for BUCK1 and BUCK2. Ground
23 PVIN_B1 — Power Power input for BUCK1. The separate power pins PVIN_Bxx are not connected together internally – PVIN_Bxx and VCCA pins must be connected together in the application and be locally bypassed. System supply
24 SW_B1 — Analog BUCK1 switch node. Floating
