hi.

there is a DCDC converter, wich has a reference voltage as 1.244V. LTC1268
the output voltage is adjustable in the usual way, Vout divided has to be = as Vref.

Because my processor core needs 1.25V@3A.

Is it possibble to use the IC, where i connect the Vfeedback pin directly to the output (without divider), to produce Vout=Vref?
 

Actually this is a boost converter, designed to have an output voltage bigger than input voltage. Generally speaking it is probably possible, the problem lies in the topology of the circuit. Why not select a different power ic already made to suit your needs?

What you need is a step-down converter or a linear one.
