LTC3855 Differential Amplifier

Hi,

Using LTC3855, I am going to design one channel to output 1V and the other to output 6.3V.

In order to use a differential amplifier, the Vout range must be 0.6V to 3.3V, and the data sheet states that it can output 0.6V to 12.5V when not in use.

I wonder if it can buck 1V on channel 1 with differential amplifier and 6.3V on channel 2 without differential amplifier.

Thanks.
