LM3687 Description
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 bined 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.
