1.5V/3.5A or 3V/2A Buck Synchronous
Charger in-One Solution for Lithium Battery
DESCRIPTION FEATURES
ETA6200 includes a 5V single cell Li+ battery linear charger
and a 1.5V/3.5A or 3V/2A buck synchronous converter.
The linear charger is fully integrated with constant current
(CC) / constant voltage (CV) control module and a charge
FET.
It also can drive a LED via output pin to indicate the charge
status.
The integrated 1.5V output buck converter is capable of
delivering 3.5A current at output.
The integrated 3V output buck converter is capable of
delivering 2A current at output.
ETA6200 is available in a DFN3x3-10 package.
