Tool/software:

How do I set the overvoltage protection to 45 volts? Also, could you please give the formula for setting the OVP?

Hi, Srinivs

The threshold in OVP pin is 1.2V. If the voltage higher than 1.2V, it will report the OVP fault.

And you will use a resistor divider connect to OVP from output.

So the formula is Vprotect = 1.2*(R1+R2)/R1.
