EA3058是高度集成電源系統管理芯片， 內部集成四路降壓轉換器主要應用于IP CAMERA ，OTT等需要多路電源轉換輸出的應用領域。EA3058使電源系統LAYOUT簡潔易用，系統更穩定。

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.
