DC-DC Boost Converters

The ams step-up (boost) converter portfolio offers very high efficiencies of up to 96%, and the devices draw a very low quiescent current. High switching speeds enable the use of very small external inductors. These DC-DC boost converters can boost the input from a single battery cell to an output of up to 42V.
