I am using UCC28610EVM-474. The o/p voltage is 12V but I need 12.6V. Can we change o/p voltage by some method.

    The UCC28610 EVM uses a simple zener diode and an optocoupler to set the output volotage to 12V in order to demonstrat the part in a cost effective application.  To adjust the voltage to a more precise value, like 12.6V, you can substitute the zener with a more traditional TL431 shunt regulator and configure it for a type II compensator.
