WEBENCH® Tools/LMZM33606: Design cannot be created

Part Number: LMZM33606

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
