DESCRIPTION  
Available in Fixed Output Voltages as well as  
an Adjustable Version  
The LM3670 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 350 mA load current, over an input  
voltage range from 2.5V to 5.5V. There are several  
different fixed voltage output options available as well  
as an adjustable output voltage version.

Internal Soft Start  
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 system  
control. During full-power operation, a fixed-frequency  
1 MHz (typ). PWM mode drives loads from ∼70 mA to  
350 mA max, with up to 95% efficiency. Hysteretic  
PFM mode extends the battery life through reduction  
of the quiescent current to 15 µA (typ) during light  
current loads and system standby. Internal  
synchronous rectification provides high efficiency (90  
to 95% typ. at loads between 1 mA and 100 mA). In  
shutdown mode (Enable pin pulled low) the device  
turns off and reduces battery consumption to 0.1 µA  
(typ.).
