... General Description The AAT2510 is a member of AnalogicTech's Total Power Management IC™ (TPMIC™) product fam- ily comprised of two 1MHz step-down con- verters designed to minimize external component size and cost. The input voltage ranges from 2.7V to 5.5V. The output voltage ranges from 0.6V to the maximum applied input voltage and is either fixed or externally adjustable ...
