The LP6312 is a 2A buck converter of 2-CH power management IC for applications powered by one Li-Ion battery or a DC 5V adapter. It integrates four synchronous buck converters and can provide highefficiency output at light load and heavy load operation. The internal compensation architecture simplifies the application circuit design. Besides, the independent enable control makes the designer have the greatest flexibility to optimize timing for power sequencing purposes. The LP6312 is available in a 10 pin DFN-10 package.
