TPS65295: Can SW pin left floating when not used?

Hi,

Due to some design requirements, we would like to use different device for a 1.2V (VDDQ) supply. Will there be any problem if SW pin is left floating?

Best regards,

    Hi, in theory, it is ok, and by the way, you need add external 1.25V source to VDDQSNS firstly to make IC thinking the VDDQ works.

    And also suggest you apply an EVM from ti.com to try it firstly.
