Hi Jim,
Can you share the schematic with us and fill in the quick start calculator: www.ti.com/.../LM5148-LM25148DESIGN-CALC
What is the output current when you have taken the attached scope capture?
Thanks,
Best Regards,
Taru
Thanks, Taylor. Send on the completed quickstart file - that's the key to determining losses, stability, etc. Also send the layout (screenshots are fine).

At the time of testing - what is the output voltage and output current?
Do you have the switch…
Hello Shunsuke,
The LM5148 requires logic level MOSFETs with a miller plateau of ~3V.
Please use the design calculator to determine losses for a given spec.
