Description
General part information
LM3686 Series
The LM3686 is a step-down DC-DC converter with a very low-dropout linear regulator and a low-noise linear regulator optimized for powering ultra-low voltage circuits. It provides three outputs with combined load current up to 900 mA over an input voltage range from 2.7 V to 5.5 V.
The device offers superior 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 (typical), PWM mode drives loads from approximately 70 mA to 600 mA maximum. Hysteretic PFM mode extends the battery life through reduction of the quiescent current to 28 μA (typical) at light load and system standby. Internal synchronous rectification provides high efficiency.
