EA3056QDR

3CH DC/DC + 1CH LDO Power Management IC EA3056 Datasheet General Description The EA3056 is a 4-CH power management IC for applications powered by one Li-Ion battery or a DC 5V adapter. It integrates three synchronous buck regulators and one N-MOS LDO in a single chip. 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 EA3056 is available in a 24 pin QFN 4x4 package.
