Description
LDO2 Feedback Input. For device models with an adjustable output voltage, connect this pin to the
middle of the LDO2 resistor divider. For device models with a factory programmed output voltage,
connect FB4 to the top of the capacitor on VOUT4.
LDO2 Enable Pin. High level turns on this regulator, and low level turns it off.
BUCK2 Input Supply (2.3 V to 5.5 V). Connect VIN2 to VIN1 and AVIN.
BUCK2 Switching Node.
Dedicated Power Ground for BUCK2.
No Connect. Leave this pin unconnected or connect to ground.
BUCK2 Enable Pin. High level turns on this regulator, and low level turns it off.
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.
BUCK2 Output Voltage Sensing Input. Connect VOUT2 to the top of the capacitor on VOUT2.
BUCK1 Output Voltage Sensing Input. Connect VOUT1 to the top of the capacitor on VOUT1.
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.
BUCK1 Enable Pin. High level turns on this regulator, and low level turns it off.
BUCK1/BUCK2 Operating Mode. MODE = high: forced PWM operation. MODE = low: auto PWM/PSM
operation.
Dedicated Power Ground for BUCK1.
BUCK1 Switching Node.
BUCK1 Input Supply (2.3 V to 5.5 V). Connect VIN1 to VIN2 and AVIN.
Analog Input Supply (2.3 V to 5.5 V). Connect AVIN to VIN1 and VIN2.
Analog Ground.
LDO1 Feedback Input. For device models with an adjustable output voltage, connect this pin to the
middle of the LDO1 resistor divider. For device models with a factory programmed output voltage,
connect FB3 to the top of the capacitor on VOUT3.
LDO1 Output Voltage.
LDO1 Input Supply (1.7 V to 5.5 V).
LDO1 Enable Pin. High level turns on this regulator, and low level turns it off.
LDO2 Input Supply (1.7 V to 5.5 V).
LDO2 Output Voltage.
Exposed Pad. It is recommended that the exposed pad be soldered to the ground plane.
