if you don't need much current ( < 0.5A ) : LT1073
regarding your nickname, I guess you're german...

german now:
das teil gibt's bei conrad ( teuer ), oder billiger bei enatechnik in quickborn, die haben aber eine mindestabnahme...

Thanks, but I am looking for a step down converter with internal DAC and up to 5 A. Yes, I can takea common SimpleSwitcher etc., but the PC mainboard converters are looking very nice and have all the stuff on chip, which I need.
