at our existing design of LT3753, a 12V to 54V converter, it seems easy to be affected by environment temperature or higher loading and might not able to continuously supply 54V/ 60 watt of PSE load. If increase the C7 from 2.2nF to 3.3nF, it seems able to supply 60 watt continuously. For changing the C7 from 2.2nF to 3.3nF, is it ok? Any side effect in real application. We needed your professional advice, Thanks a lot!
Below is our existing schematics and part of PCB layout.
