This is valid for devices where foldback current limit is enabled. If interested in this option, please contact Texas Instruments.
When the device detects current limit for more than 1024 subsequent switching cycles, it reduces the current limit from its nominal value to typically 1.3 A. Foldback current limit is left when the current limit indication goes away. If device operation continues in current limit, it can, after 3072 switching cycles, try for full current limit again for 1024 switching cycles.
