TPS65296: Using TPS65296 with only one VDD

Part Number: TPS65296

Hi,

TPS65296 has two VDD: VDD1 and VDD2, since my customer only request VDD2 for power supply. we would like to know how to deal with VDD1?

1)CAN we float PIN-SW_VDD1?

2)Can we connect PIN-VDD1SNS to 1.8v since we prefer to use PGOOD to montior VDD2;

3)Or can we connect PIN-VDD1SNS and PIN-VDD2SNS?
