LM5001: LM5001 Vout=40V Iout=180mA, Vout occasionally droped to 10V

Hi Eli,

Can you share the layout of your board? 

Have you checked the SW, VOUT waveform?

Thaks for your reply.I haven't check the SW, VOUT waveform.I tryed to reproduce this problem,but LM5001 now working normally for about 24 hours. Is it possible that environment temperature or quicked

 changed load caused this problem? 6.8uH/8A inductance(L1) and 150uH/500mA inductance(L1) now are all works well,we used 6.8uH/8Afor mass production,did we need to change L1for 150uH?

Hi Eli,

Glad to hear that. Did you use the same PCB for two times?

Both 6.8uH and 150uH would work well. It depends on you.

Yes,I used the same PCB for two times.

OK. We will do more test.
