I have designed a DC-DC buck power supply with a LM5116-HT. I am attaching the schematic, PCB layout file(Both are in Altium) and the Gerbers.
I am having issues with the following issues with the power supply:
1. There is no output voltage.
2 There is a periodic negative pulse on the UVLO line (scope trace attached).
3 I have tried 2 different FETs, 2 different PCB layouts and still not getting the output to work.
Has anyone else seen this problem before? I need some suggestions on how to proceed to make this work.
