上海鈺泰（ETA) 2A開關(guān)充電器ETA9741，ETA9741E8A現(xiàn)貨熱銷

        ETA9741 is a switching Li-Ion battery charger capable of delivering 2A of charging current to 

the battery and also capable of delivering up to 5V/2.4A in boost operation, with high efficiency in 

both charging mode and boost mode. It also includes a fuel gauge system for power indication. 

For charging, it uses a proprietary control scheme that eliminates the current sense resistor for 

conventional constant current control, maximizing efficiency, reducing charging time and reducing 

costs. It can also output a 5V voltage in the reversed direction by boosting from the battery.
