Yes, I also see no difference. In general, I obey that there is a tendency to put integrated circuits in huge market segments like LED and SMPS. This makes it harder for developers to find devices for particular purposed. I think that the trend is simply due to trying to obtain a bigger market share by labeling the same device with different names and different feature set in the datasheet.
