9. Functional Description

9.1. Charge Mode

The SW6206 integrates a switching charger with efficiency is up to 96%. The switching charger

supports 4.2V/4.35V/4.4V/4.5V battery voltage. Its switching frequency is up to 400KHz, so a small

size inductor with inductance of 2.2uH can be used.

The switching charger charges battery in three charge phases: trickle charge(TC), constant current
