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 combined 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. There are  
several different fixed output voltage combinations  
available (refer to Voltage Options).

Combined Common Features:  
The Linear Regulator being driven from the fixed  
output voltage of the buck converter (post regulation)  
translates to high efficiency.  
The device offers superior features and performance  
for mobile phones and similar portable applications  
with complex power management systems. Automatic  
intelligent switching between PWM low-noise and  
PFM low-current mode offers improved efficiency  
over the full load current range. During full-power  
operation, a fixed-frequency 1.8MHz (typ.) PWM  
mode drives loads from ~80mA to 750mA max.  
Hysteretic PFM mode extends the battery life through  
reduction of the quiescent current during light loads  
and system standby.

Independent Mode of Operation (DC-DC:  
750mA, Linear Regulator: 350mA)
