TPS546C20A: TPS546C20 Two Phase mode

TPS546C20 Two Phase  mode:

 1,Can you work in a hardware-only way without PMBUS?

  2,Since the PM_BUS feature is not used, protection functions such as OCP/OVP/UVP are implemented on external lines. Please also confirm what is the default OCP/OVP/UVP protection point within the IC and how to adjust it to avoid conflict with the protection point on the external line?

    Mark,

    I am reasonably sure the TPS546C20 can be set for sharing by tying the FB pin of the slave device to BP3, then connecting VSHARE, ISHARE and SYNC pins together as detailed in the datasheet. The default values are OCP = 37 A, OVP = 117%, UVP = 83%. They cannot be adjusted without PMBus control.
