The LTC3255’s key attributes and performance differentiators are: an input voltage range of 4V to 48V; an adjustable regulated output of 2.4V to 12.5V; 16μA quiescent current in regulation at no load; input fault protection from –52V to 60V; multimode charge pump (2:1, 1:1) with automatic mode switching, which maintains regulation over wide VIN range; input voltage shunt mode for current-fed applications; over-temperature and short-circuit protection; high operating junction temperature of 150°C maximum; and thermally enhanced 10-lead MSOP and 10-lead 3mm × 3mm DFN packages.
