I have read the posts from Alex Chepyga and Anston Lobo and am having a similiar problem. Using the design reference per the specifications, on a bread board, tighly wired together, the part is damaged if I immediately apply >12V which im my case may be 14v or 18v-24v. If I turn on a variable DC supply and bring up the voltage slowly, no problem. I have ordered the evaluation board to see if it works. WEB Bench does not acknowledge using greaer than 12V which suggests a die problem. I also ordered some LM2842XMK-ADJL and LM22675MR-ADJ which has a bilt in soft start. From the threads I read, soft start must be needed for my application, yet I cannot find any application notes to specify designs. I also read about short circuit issues for my application of >12v inputs. Please let me know if I am pursuing a faulty design for my application. Thank you.
