ETA9880 Datasheet | ETA

DESCRIPTION FEATURES ETA9880 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. ETA9880 includes a power path from IN to OUT, a buck charger, a 5V boost converter, and a fuel gauge for power 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 , ETA9880 is an ideal all-in-one solution for Li+ battery charging, discharging applications. ETA9880 is available in ESOP8 package. - 20V Input Standoff Voltage - Bi-Directional Power Conversion with Single Inductor - Power Path from IN to OUT - Automatic Mode Switching - Switching Charger - 5V Synchronous Boost - Up to 96% Efficiency - No External Sense Resistor - LEDs for Battery Level Indication and Charge/Discharge Status Indication - Ro HS pliant APPLICATIONS - Power Bank - Li+ Battery Powered System TYPICAL APPLICATION 10u F Optional VIN D2 D4 1 IN EP GND 3.3n F 22u Fx2 10u F VOUT 8 1Ω 2 LED1 SW 7 2.2u H D1 3 LED2 D3 4 LED3 BAT 6 PB 5 Torch VOUT Li+ Battery ORDERING INFORMATION .etasolution.
