Need internal VRM values of inductance and ESR for said device.
Rvrm and Lvrm
Hey Dhruv,
Thank you for using E2E,
May I know the purpose of getting this values?
In case if you are interested in load regulation, please provide me the operating conditions so that I can share you the results.
Thank you & regards,
Moheddin.
Hi Moheddin,
Thanks for your response. We actually need this value for PI simulation of our core SoC voltage rail.
Our decoupling network has the following z-profile:
We used sample values from this thread: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/716640/lmz31530-vrm-resistance-and-inductance-values
and were able to get a much more reasonable Z11:
Hey Dhruv,
Let me check for this values and get back to you.
Thank you & regards,
Moheddin.
Hey Dhruv,
Resistance is around 2m to 2.5mOhm & inductance is around 0.5nH to 1nH.
Thank you & regards,
Moheddin.
