Tool/software: WEBENCH® Design Tools
Hi Team,
Our customer is simulating with LMZM33606 in WEBENCH with the following conditions:
Vout = 12V
Vin = 24V typical
Vin lowest = 13.5V (When operating from battery)
Output Current = 4A or higher
However, WEBENCH was unable to create the design due to stability issues caused by phase margin being beyond 35°-120°. Can you help us identify what is causing this?
Aside from minimum Vin being 1.1*Vout, are there any other considerations to keep in mind on these operating conditions?
Thank you very much in advance.
Kind Regards,
Jejomar
Hi Jejomar,

Hi Jejomar,
We have fixed the issue now. The changes will be moved to TI web in our next production release.
Thanks and Regards,

Hello Atul,
This is noted. We'll impart this to our customer. We tried simulating on other operating conditions and they managed to agree on a 13.8V input which gave them a desirable design.
Thank you very much for your help!
Kind Regards,
Jejomar
