ETA9881 20V Standoff, 2.4A Charger and 2.4A Boost for Power Bank All-in-One Solution DESCRIPTION FEATURES ETA9881 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. ETA9881 includes a power path from IN to OUT, a buck charger, a 5V boost converter, and a fuel gauge for power indication. It also has NTC monitor and DCP function. 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.
