2.5 Output-voltage Tracking

For TPS54J06x, the SS/REFIN pin can be used as an analog input to accept an external reference. When an external voltage signal is applied to SS/REFIN pin, it acts as the reference voltage, thus the FB voltage follows this external voltage signal. TPS54J06x data sheet describes the details.
