The LM3370 is a dual step-down DC-to-DC converter for driving ultra-low voltage circuits ranging from 2.7V to 5.5V input rails from a single lithium-ion battery. It provides two outputs per channel load of 600 mAh. The output voltage range is from 1V to 3.3V, and the use of I can be dynamically controlled 2 C compatible interface. This dynamic voltage amp capability enables the highest level of performance with the lowest power consumption of the processor. It's in me 2 The C-compatible interface can also be used to control performance-enhancing features such as automatic PFM-PWM/PWM mode selection.

The LM3370 offers superior functionality and the performance of a portable system for complex power management requirements. Intelligent switching between automatic PWM low noise and PFM low current modes provides improved system efficiency. Internal synchronous rectification improves efficiency without further external devices using the converter.

There is a power-on reset function to monitor the output voltage level to avoid unexpected power loss. Independently of each output enable pin allows for simple and efficient power sequencing.

The LM3370 is a micro SMD available in 4 mm, 5 mm, 16-pin non-pull LLP and 20 bump packages in 3.0 mm× 2.0 mm× 0.6 mm. The high switching frequency of 2 MHz (typical) allows for tiny surface-mount components, including a 2.2μH inductor.
