Pin No. Mnemonic Description
1
AGND
Analog Ground.
2
AGND
Analog Ground.
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.
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 an adjustable output voltage, connect this pin to the middle of the
BUCK2 resistor divider. For device models with a 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 an adjustable output voltage, connect this pin to the middle of the
BUCK1 resistor divider. For device models with a 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 for forced PWM operation. MODE = low for automatic 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
LDO Feedback Input. For device models with an adjustable output voltage, connect this pin to the middle of the
LDO resistor divider. For device models with a fixed output voltage, connect this pin to the top of the capacitor
on VOUT3.
20
VOUT3
LDO Output Voltage.
21
VIN3
LDO Input Supply (1.7 V to 5.5 V).
22
EN3
LDO Enable Pin. High level turns on this regulator, and low level turns it off.
23
AGND
Analog Ground.
24
AGND
Analog Ground.
EPAD (EP) Exposed Pad. It is recommended that the exposed pad be soldered to the ground plane.
