TIDA-00653: Questions about reference design

Part Number: TIDA-00653
Other Parts Discussed in Thread: UCD3138128

Hello,

I'm working on a project that has similar specs to the TIDA-00653 for an automotive application. I just had a few questions about the design:

1. My output voltage is in the range of 11.5 V to 14.5 V, 14 V nominal. To meet this spec, I figured I would change the feedback resistor values, as well as use higher voltage rating capacitors at the output. Would TI recommend any additional changes?

2. Does the UCD3138128 support CAN? I could not find any information in the datasheet but I noticed the CAN transceiver in the schematic.

Thanks,

Tharindu
