LM3691  
SNVS506J MAY 2008REVISED DECEMBER 2015  
LM3691 High-Accuracy, Miniature 1-A Step-Down DC-DC Converter  
for Portable Applications  
1 Features  
3 Description  
The LM3691 step-down DC-DC converter is  
optimized for powering ultra-low-voltage circuits from  
a single Li-Ion cell or 3 cell NiMH/NiCd batteries. It  
provides up to 1-A load current over an input voltage  
range from 2.3 V to 5.5 V. There are several different  
fixed voltage output options available.

Input Voltage: 2.3 V to 5.5 V  
Output Voltage: 0.75 V to 3.3 V  
±1% DC Output Voltage Precision  
4-MHz Switching Frequency  
64-μA (typical) Quiescent Current in ECO Mode  
1-A Maximum Load Capability  
The LM3691 has a mode-control pin that allows the  
user to select Forced PWM mode or ECO mode that  
changes modes between gated PWM mode and  
PWM automatically, depending on the load. In ECO  
mode, the device offers superior efficiency and very  
low IQ under light load conditions. ECO mode extends  
the battery life through reduction of the quiescent  
current during light load conditions and system  
standby.  
Automatic ECO/PWM Mode Switching  
MODE Pin to Select ECO/Forced PWM Mode  
Current Overload and Thermal Shutdown  
Protections  
Only Three Tiny Surface-Mount External  
Components Required (Solution Size Less Than  
15 mm2)  
The LM3691 is available in a 6-pin DSBGA package.  
Only three external surface-mount components, a  
1-μH inductor, a 4.7-μF input capacitor, and a 4.7-μF  
output capacitor, are required.  
2 Applications  
Mobile Phones  
Hand-Held Radios
