TPS629210: VSET internal voltage divider versus FB external voltage divider

Part Number: TPS629210


What is the intended usage of the VSET internal voltage divider? Just one less external component required?

Are there any obvious pros/cons I am missing? It seems to function nearly identically to the FB external voltage divider mode.

The only difference I can find is Table 8-1 from the datasheet (below) indicates that dynamically switching modes between Auto PFM/PWM and Forced PWM can only be done when using external FB.

Is this the only consideration?

Thanks for your time
