LTM4607 operation

Hi, could you please provide some insight into LTM4607 operation?

What will happen if the external feedback resistor value is selected so low that the output will try to go above 25V? Is the absolute maximum rating of Vout=25V something that the part limits it to, or is this something the design has to make sure does not happen?

In my case the input voltage is 28V. The reason I'm asking this question is that I need to have the output voltage (or current) controlled digitally, so I wanted to use a feedback loop instead of the resistor (providing 0.8V on Vfb pin in steady state).

Thanks in advance,


A related question: the datasheet mentions "overvoltage protection". How exactly does it work? What condition(s) does it protect from?
