Table 8. Pin Function Descriptions
Pin No. Mnemonic Description
1 FB4 LDO2 Feedback Input. For device models with adjustable output voltage, connect this pin to the middle of the
LDO2 resistor divider. For device models with fixed output voltage, connect this pin to the top of the capacitor on
VOUT4.
2 EN4 LDO2 Enable Pin. High level turns on this regulator, and low level turns it off.
3
VIN2
BUCK2 Input Supply (2.3 V to 5.5 V). Connect VIN2 to VIN1 and AVIN.
4 SW2 BUCK2 Switching Node.
5 PGND2 Dedicated Power Ground for BUCK2.
6 NC No Connect. Leave this pin unconnected or connect to ground.
7 EN2 BUCK2 Enable Pin. High level turns on this regulator, and low level turns it off.
8 FB2 BUCK2 Feedback Input. For device models with adjustable output voltage, connect this pin to the middle of the
BUCK2 resistor divider. For device models with fixed output voltage, leave this pin unconnected.
9 VOUT2 BUCK2 Output Voltage Sensing Input. Connect VOUT2 to the top of the capacitor on VOUT2.
10 VOUT1 BUCK1 Output Voltage Sensing Input. Connect VOUT1 to the top of the capacitor on VOUT1.
11 FB1 BUCK1 Feedback Input. For device models with adjustable output voltage, connect this pin to the middle of the
BUCK1 resistor divider. For device models with fixed output voltage, leave this pin unconnected.
12
EN1
BUCK1 Enable Pin. High level turns on this regulator, and low level turns it off.
13 MODE BUCK1/BUCK2 Operating Mode. MODE = high: forced PWM operation. MODE = low: auto PWM/PSM operation.
14 PGND1 Dedicated Power Ground for BUCK1.
15 SW1 BUCK1 Switching Node.
16 VIN1 BUCK1 Input Supply (2.3 V to 5.5 V). Connect VIN1 to VIN2 and AVIN.
17 AVIN Analog Input Supply (2.3 V to 5.5 V). Connect AVIN to VIN1 and VIN2.
18 AGND Analog Ground.
19 FB3 LDO1 Feedback Input. For device models with adjustable output voltage, connect this pin to the middle of the
LDO1 resistor divider. For device models with fixed output voltage, connect this pin to the top of the capacitor on
VOUT3.
20 VOUT3 LDO1 Output Voltage.
21 VIN3 LDO1 Input Supply (1.7 V to 5.5 V).
22 EN3 LDO1 Enable Pin. High level turns on this regulator, and low level turns it off.
23 VIN4 LDO2 Input Supply (1.7 V to 5.5 V).
24 VOUT4 LDO2 Output Voltage.
EPAD (EP) Exposed Pad. It is recommended that the exposed pad be soldered to the ground plane.
