LM51231-Q1: How to get Bode plot

Youhei Miyaoka

Part Number: LM51231-Q1

Hi team,

My customer have question about bode plot for phase margin.

They inject 50~100Ohm in following red block and measure by network analyzer.

Does this measurement work well?

Hi Youhei,

Thank you for using E2E forums, regarding your query yes this red block or resistor should be fine and should work.

In the LM5123-EVM if you look we have a similar resistor placement at this pin.

Hope this helps

BR,

Haroon
