LT3753 OCP triggered unexpectedly

Question

Hi Madam/Sir, 
 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.

Hi, 
 This should not have a significant effect as it only acts as a filter. However, you should check the characteristic datasheet of the capacitor you will be using how it behaves in different environment (humidity, temperature, altitude, etc.) depending on what applies on your application.
