LM3370  
Dual Synchronous Step-Down DC-DC Converter with  
Dynamic Voltage Scaling Function  
General Description  
Features  
The LM3370 is a dual step-down DC-DC converter optimized  
for powering ultra-low voltage circuits from a single Li-Ion bat-  
tery and input rail ranging from 2.7V to 5.5V. It provides two  
outputs with 600 mA load per channel. The output voltage  
range varies from 1V to 3.3V and can be dynamically con-  
trolled using the I2C compatible interface. This dynamic volt-  
age scaling function allows processors to achieve maximum  
performance at the lowest power level. The I2C compatible  
interface can also be used to control auto PFM-PWM/PWM  
mode selection and other performance enhancing features.

Internal synchronous rectification for high efficiency  
Internal soft start  
The LM3370 offers superior features and performance for  
portable systems with complex power management require-  
ments. Automatic intelligent switching between PWM low-  
noise and PFM low-current mode offers improved system  
efficiency. Internal synchronous rectification enhances the  
converter efficiency without the use of further external de-  
vices.  
Power-on-reset function for both outputs  
2.7V ≤ VIN ≤ 5.5V  
Operates from a single Li-Ion cell or 3 cell NiMH/NiCd  
batteries and 3.3V/5.5V fixed rails  
2.2 µH Inductor, 4.7 µF Input and 10 µF Output Capacitor  
per channel  
■
There is a power-on-reset function that monitors the level of  
the output voltage to avoid unexpected power losses. The in-  
dependent enable pin for each output allows for simple and  
effective power sequencing.  
16-lead LLP Package (4 mm x 5 mm x 0.8 mm)

■
20-Bump micro SMD Package (3.0 mm x 2.0 mm x 0.6  
mm)  
LM3370 is available in a 4 mm by 5 mm 16-lead non-pullback  
LLP and a 20-Bump micro SMD, 3.0 mm x 2.0 mm x 0.6 mm,  
package. A high switching frequency—2 MHz (typ)—allows  
use of tiny surface-mount components including a 2.2 µH in-  
ductor.
