The LM3370 is a dual step-down DC-DC converter optimized
for powering ultra-low voltage circuits from a single Li-Ion battery
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 controlled
using the I2C compatible interface. This dynamic voltage
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.
The LM3370 offers superior features and performance for
portable systems with complex power management requirements.
Automatic intelligent switching between PWM lownoise
and PFM low-current mode offers improved system
efficiency. Internal synchronous rectification enhances the
converter efficiency without the use of further external devices.
