Part Number: LM21215A Tool/software: Hello,
I have some questions about the COMP pin design of the LM21215A.
Q1. Could you please elaborate the function of the COMP pin?
Q2. Typically, users follow the TI Webench simulation results for the component…
Hi Chris, Umayal
Thanks for your kind reply.
Could you explain why the output noise is improved when only the COMP pin connection value of the 2024 Webench design is changed on a board designed with reference to the 2022 Webench design of LM21215A?
The…
Part Number: LM21215A Hello,
I am running output ripple analysis on LM21215A power converter. the simulation runs from 100Hz to 1MHz. I can't find any option on Webench to change this frequency range, to 100MHz. Also, how can I save my custom design in…
Part Number: LM21215A Hi,
we have bought 5Kpcs of LM21215AMHX-1/NOPB on 27th Feb under sales order T0487344. We found bottom pad shows retinned pad and bottom surface is uneven, as shown in the attached picture. Please help to make sure this part is brand…

Part Number: LM21215A Just to mention, that I think the formula for fZ2 in the datasheet (SNOSB87C –MARCH 2011–REVISED JANUARY 2016, Rev C.) is incorrect on page #23, it should be RC2 instead of RC1. The webench seems to calculate the poles and zeros…
