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

DESCRIPTION

FEATURES

ETA9687 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 ETA9687. Simple MCU functions are

also included in ETA9687, such as, push-button, USB

charging emulation, no load detection. All of these

highly integrated features of ETA’s Power SOC+

technology make ETA9687 an ideal solution for

Power bank or applications alike.

ETA9687 is available in ESOP-8 package.
