LM5008A: LM5008ASDX/NOPB

Hello,

What is the saturation current of your inductor? You must make sure the saturation current is well below the peak ripple current.

Please double check that or share the part number with me,

Thank you very much for replying me.I  selected WE inductor ,partnumber is 74404084331,it's information just in below 1 ,i  also tried WE inductor 74404086471,its information just in below 2,it has higner Isat and high L，but it also has a serious fever.HOW can i due this like problem?

What output current are you running at?

For both those inductors the rated current is similar (0.65A) and with that current the temperature rise ΔT will be 40C.

Does it get hot at no-load?

Now i have solved that bug，but now  LM5008A does not have a output?why?I have test the input ,it provise 24v,but no current input,only pin8 can test 24v,but other pins can test nothing，why?

it get hot at no-load，ihave solved the bug ,because it has a short circuit，but when i solved that problem，with a new PCB but new problem just LM5008a doed not have a output have occured?why it does not have a output?which aspect can i tackle this situation?
