2.2.2 Output Voltage Setting

The output voltage of U1 is set to a default of 0.75 V. Other default voltages can be set using appropriate values for the resistors R5 and R6. During operation, the output voltage can be changed using the I2C interface. For more details, see the TPS6287x-Q1 Low Input Voltage, Adjustable-Frequency Step-Down Converter data sheet.
