Automatic PFM/PWM Mode Switching  
Internal Synchronous Rectification  
Internal Soft Start  
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.

VOUT_LILO = 0.7 V to 2 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.
