Additional preview pages of the MAX1672 datasheet.

The MAX1672 integrates a step-up DC-DC converter with a linear regulator to provide step-up/down voltage conversion.

This device provides a constant output voltage for inputs that vary above and below the output voltage.

It has a 1.8V to 11V input range and a preset 3.3V or 5V output.
