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.

Highly efficient LED drivers provide optimal performance in general lighting applications and in LED backlighting systems for large flat display panels.
ams supervisors offer high accuracy and low power consumption. In battery-powered systems in particular, the supply must be monitored in order to perform safe start-up and shut-down operations.
