Hello,
I have been studying the UCC28950 device for use up to 48v / 50A Power Level.
Studying the 12v eval module the transition between DCM and CCM is very smooth - however when I adjust for 48v operation a large phase shift / jump is observed at my desired DCM to CCM point.
I looks like maximum duty is immediately applied (not at full load though!)
Can anybody confirm why this occurs?
