The EA3038 is a 3CH power management IC for applications powered by one Li-Ion battery or a
DC 5V adapter. It integrates three synchronous buck converters and can provide high efficiency
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 EA3038 is available in a
20 pin QFN 3x3 package.
