Table 5-1 Pin Functions
PIN I/O DESCRIPTION
NO. NAME
A1 EN I Device enable. A high logic level on this pin enables the device; a low logic level on this pin disables the device.
A2, A3 VIN PWR Supply voltage for power stage
B1 ADDR I I2C target address selection pin.

ADDR = Logic low, I2C target address is 0x75

ADDR = Logic high, I2C target address is 0x76

ADDR = floating, I2C target address is 0x77
B2, B3 LX1 PWR Inductor connection
C1 AGND — Analog ground
C2, C3 GND PWR Power ground
D1 SCL I/O I2C serial interface clock. Pull this pin up to the I2C bus voltage with a resistor.
D2, D3 LX2 PWR Inductor connection
E1 SDA I/O I2C serial interface data. Pull this pin up to the I2C bus voltage with a resistor.
E2, E3 VOUT PWR Converter output
