Conversion efficiency: 3A 93%, 2A 94%, 1A 95% (data for reference only)

The IP2312 adopts a full CC/CV charging mode.

When the battery voltage is lower than 3V, it enters the trickle charging mode and charges the battery with a charging current of 100mA.

When the battery voltage is greater than 3V, it enters the constant current charging mode to charge the battery with the set constant current charging current.

When the battery voltage is close to 4.2V and the charging current is less than 300mA, it enters the constant voltage charging mode. After entering the constant voltage mode, stop charging every 4 minutes, and check whether the battery voltage is higher than 4.15V: if it is higher than 4.15V, stop charging; otherwise, continue charging, and then check after 4 minutes.

When the battery is fully charged, if it detects that the battery voltage is lower than 4.1V, it will turn on to charge the battery again.
