Hi TI Support,
When I read the datasheet, it says that it has output short-circuit protection. But, on the same page also, it says, "Because the regulator is floating and receives only the input-to-output differential voltage, supplies of several hundred volts can be regulated as long as the maximum input to output differential is not exceeded; do not short-circuit output to ground." I assumed that since the IC has current limit of 5A and differential voltage between the input and output is 30V, when it tries to limit the current from short circuit, it cannot do it so it will blow up. But, if the differential voltage is less than 30V, it will succeed to limit the current.
Therefore, based on this assumption, I tested it, but it didn't work. It blew up instead, with the IC broken up to 2 pieces. That made me scratching my head, where is the short-circuit protection? Can you kindly explain how does the short circuit protection work? What would be the best protection aside from using fuse at the output?
