LM3687TLX-1812/NOPB Description

The LM3687TLX-1812/NOPB 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-lon cell or 3-cell NiMH/NiCd batteries. The LM3687TLX-1812/NOPB provides a dual output with fixed output voltages and combined load current up to 750mA in post-regulation mode or 1100mA in the 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 Voltage Options).
