Pin Description
PIN
NAME
FUNCTION
A1
LDO1
300mA LDO1 Output. Bypass LDO1 to AGND with a 2.2FF ceramic capacitor. The output voltage
is programmable from 1.6V to 3.3V in 100mV steps. The output impedance of LDO1 is 300I when
disabled with the LDO1_ADEN bit set to 1.
A2
LDO2
300mA LDO2 Output. Bypass LDO2 to AGND with a 2.2FF ceramic capacitor. The output voltage
is programmable from 1.2V to 3.3V in 100mV steps. The output impedance of LDO2 is 300I when
disabled with the LDO2_ADEN bit set to 1.
A3
LDO3
300mA LDO3 Output. Bypass LDO3 to AGND with a 2.2FF ceramic capacitor. The output voltage
is programmable from 1.6V to 3.3V in 100mV steps. The output impedance of LDO3 is 300I when
disabled with the LDO3_ADEN bit set to 1.
A4
BATT
Supply Voltage to the Control Section, LDO2, LDO3, and USB Switch. Connect a 2.2FF ceramic
capacitor from BATT to AGND.
A5
IN1
Supply Voltage to the Step-Down Converter. Connect a 2.2FF input ceramic capacitor from IN1 to
PGND.
A6
LX
Inductor Connection for Step-Down Converter. LX is internally connected to the drain of the internal
p-channel MOSFET and the drain of the internal n-channel synchronous rectifier. The output impedance
of LX is 300I when the step-down converter is disabled with the BUCK_ADEN bit set to 1.
B1
REFBP
Reference Noise Bypass. Bypass REFBP to AGND with a 0.1FF ceramic capacitor to reduce noise on
the LDO outputs. REFBP is high impedance in shutdown.
B2
CB
Digital Control Input for USB High-Speed Switch. Drive CB low to connect COM1 to NC1 and COM2 to
NC2. Drive CB high to connect COM1 to NO1 and COM2 to NO2.
B3
ENUSB
Active-Low Enable Input for USB High-Speed Switch. Drive ENUSB high to put the switch in high
impedance. Drive ENUSB low for normal operation.
B4
ENLDO1
Enable Input for LDO1. Drive ENLDO1 high to turn on the LDO1. Drive ENLDO1 low to turn off the LDO1.
LDO1 can also be enabled/disabled through the I2C interface. ENLDO1 and I2C control bit are logically
ORed. ENLDO1 has an internal 800kI pulldown resistor.
B5
ENBUCK
Enable Input for the Step-Down Converter. Drive ENBUCK high to turn on the step-down converter.
Drive ENBUCK low to turn off the step-down converter. The step-down converter can also be enabled/
disabled through the I2C interface. ENBUCK and I2C control bit are logically ORed. ENBUCK has an
internal 800kI pulldown resistor.
B6
PGND
Power Ground for Step-Down Converter
C1
IN2
Supply Voltage to LDO1, LDO4, and LDO5. Connect a 2.2FF input ceramic capacitor from IN2 to AGND.
