3-CH Power Management IC EA3059C
General Description

The EA3059C is a 3-CH power management IC for applications powered by one Li-Ion battery or a DC 5V adapter.

It integrates three synchronous buck regulators 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 EA3059C is available in a 24 pin QFN 4x4 package.
