    Lei,

    B1, B2 can be connected to BAT. the input of the DC-DC is internally from PMID. PMID will be either VIN or VBAT level. For LS/LDO to function, you will need to connect VINLS to either PMID or VSYS. Please follow the EVM schematic and datasheet and let us know if you have any questions. :)
