LM3431 Type 1 fault

Other Parts Discussed in Thread: LM3431

Dear Sir,

I have a question about Type 1 fault of LM3431, according to datasheet  page 22, it mentioned that For a Type 1 fault, the LM3431

will continue to regulate, although the DLY pin remains high. In this condition, the DLY pin will charge to a maximum of 3.6V (typical).


what will happen once one LED string open or short?  if we neglect the fail string, does the others string will work properly?

Does that means  the regulators will continue to operate without problem? Thanks.
