Part Number: UCC25600
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?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Hi Eric Faraci,
thank you for the explanation.
i have two problems:
1) in the case of UCC25600, in the PMP5967 reference design, the input/output voltage ratio is approximately 32 ( ie 380/12 ). the performance of the design seems high.
2) in your answer, do you consider adjusting output voltage, when converter works or in the develop stage?
