Hi,
I am planning on using UCC25600EVM evaluation board as a second stage of my converter. The power stage preceding the LLC outputs a DC voltage that varies between 380 to 430 V. User guide for UCC25600EVM states that the maximum input voltage can be upto 405 V. Can you kindly tell if the input voltage range for the evaluation board be increased to 450 V. In that case, what components will be required to be replaced.
Secondly, can you tell the bandwidth of the feedback loop that regulates the output voltage at 12 V.
