EA3058是高度集成电源系统管理芯片， 内部集成四路降压转换器主要应用于IP CAMERA ，OTT等需要多路电源转换输出的应用领域。EA3058使电源系统LAYOUT简洁易用，系统更稳定。

General Description

The EA3058 is a 4-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 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 EA3058 is available in a 
24 pin QFN 4x4 package.
