For the title of your post, please begin with the part number and then state your actual question.

This is specified directly below in the feedback voltage parameter.

The newer TLV62080 allows higher currents and a wider output filter.

Thank you Chris.

In other words ...
When this device is moved in PFM mode , VFB accuracy is this OK?

☆VFB accuracy @PFM Mode: 2.5% (Vref accuracy) + 1.0% (Dynamic Voltage Positioning)

Could you tell me?

Yes, this is basically correct.

The TLV62080 does not have this dynamic voltage positioning feature and thus provides a more accurate Vout.
