(1) In order to be consistent with the TI reliability requirement of 100k Power-On-Hours at 105°C junction temperature, the output current should not exceed 6A continuously under 100% duty operation as to prevent electromigration failure in the solder. Higher junction temperature or longer power-on hours are achievable at lower than 6A continuous output current.
