TPS65083x VDDLV and LVA pin

Hi,

How should we connect VDDLV and LVA pins if they're not used?  My previous understanding is that VDDLV needs to be connected to either LDO3V or VR3 output no matter it's used or not, am I right?  Can we connect it to the V3.3A_PCH?

Can we just keep LVA/LVB unconnected on board?

Thanks!

Antony
