Hi,
I have created a PCB board similar to the demo DC42044A
The input is a regulated 30V from a power supply and the output is set to be 11.1V 3.3A.
The issue is that when turned on the power supply is current limited and will only allow ~6.6V @ 0.5A to pass through and the VOUT output of the board is capped at ~7.9V
I've tried to troubleshoot this myself by changing the feedback resistors but have had no luck thus far.
My expertise is not in power electronics so apologies in advance for any obvious misses.
Schematics, Board Layout snips, Gerber Files and Oscilloscope readings are all in the ZIP file below.
