Which is not uncommon in multi-output switchers. Not at all unusual to see the main (e.g. 5V) output directly regulated, but secondary outputs handled by 78xx/79xx linear regulators. That's not to say that the secondary outputs can't be switch-regulated. The "simple switcher" ICs are well-suited to that application. --Chuck
