Powering Minds of the Smart

Power SOC+ with 5V/2.1A Output and 1A linear Charger

DESCRIPTION

FEATURES

ETA9689 belong to a series of ETA Solutions pioneered

Power SOC+. It is capable of delivering 2.1A at the 5V

output and can charge at its input with up to 1A charging

current. A highly integrated synchronous boost

converter that can provide efficiency as high as 97% and

a simple linear charge that provides fast charge current

up to 1A are both integrated in ETA9689. Simple MCU

functions are also included in ETA9689, such as, push-

button, USB charging emulation, no load detection. All of

these highly integrated features of ETA’s Power SOC+

technology make ETA9689 an ideal solution for Power

bank or applications alike.

ETA9689 is available in DFN3x3-12 package.
