UCC25600: wide range output

Part Number: UCC25600

Dear All,

i selected the UCC25600 for a 400 W resonant converter.

the problem is that i need to adjust the output voltage of a resonant converter when it works.

the output voltage has a wide range from 0 to 400 V.

the input voltage is 400 V ( form UCC28019A PFC stage ).

the maximum current is 1 A and the load is a  resistance ( variable resistance 400 W ).

please see the bellow schematics ( form data sheet ):

can i adjust the voltage by change the Vs?

or can i adjust the voltage by changing the upper resistance in the divider?

or is there any other methods to do that?
