LM3686, Step-Down DC-DC Converter
The LM3686 is a step-down DC-DC converter with one integrated very low dropout linear regulator and a low noise linear regulator optimized for powering ultra-low voltage circuits from a single Li-Ion cell or 3 cell NiMH/NiCd batteries.
It provides three outputs with combined load current up to 900 m
LM3686 Features
* and performance for many applications. Automatic intelligent switching between PWM low-noise and PFM low-current mode offers improved system control. During full-power operation, a fixed-frequency 3 MHz (typ.), PWM mode drives loads from ~70 mA to 600 mA max. Hysteretic PFM mode extends the battery
