ETA9882 20V Standoff, 2.4A Charger and 2.4A Boost for Power Bank All-in-One Solution
■ETA9882 is a switching Li-Ion battery charger capable of delivering up to 2.4A of charging current to the battery and also capable of delivering up to 2.4A in boost operation. ETA9882 includes a power path from IN to OUT, a buck charger, a 5V boost converter, and a charge status indication. The buck charger guarantees a 93.5% average efficiency at 2.4A charge current and the boost converter achieves 92% efficiency at 2.4A output when battery voltage is as low as 3.3V. It greatly increases the effective battery capacity for a battery powered system, such as power bank. With all these features, ETA9882 is an ideal all-in-one solution for Li+battery charging, discharging applications.
■ETA9882 is available in ESSOP10 package.
