DC-DC Step up Converters

austriamicrosystems Step up Converters portfolio is optimized for highest efficiencies of up to 96% and lowest quiescent currents. High switching speeds enable the use of very small external inductors. Furthermore DCDC boost converters are offered capable to boost voltages up to 42V from a single battery cell.
