Thread Summary

                The user inquires about increasing the max Vin beyond 18V for the dev kits, noting the LT8253's max Vin of 40V. The final answer explains that the 18V limit is a firmware constraint for the USB port controller and can be reconfigured, as the application is designed for automotive input voltage ranges but can tolerate higher voltages.

The user manuals state the max Vin is 18V for both dev kits.  Is there a way to increase the max Vin?  Why is the set to 18V since the LT8253 has a max Vin of 40V?
