The LM3687 is a step-down DC-DC converter with an integrated
low dropout Linear Regulator optimized for powering
ultra-low voltage circuits from a single Li-Ion cell or 3 cell
NiMH/NiCd batteries. It provides a dual output with fixed output
voltages and combined load current up to 750mA in post
regulation mode or 1100mA in independent mode of operation,
over an input voltage range from 2.7V to 5.5V. There are
several different fixed output voltage combinations available
(refer to table 'Voltage Options').
