Simulating synchronous buck with SPICE components (MOSFTE/Drivers)

Hello all,

I’m exploring the SPICE feature by trying to simulate a synchronous buck, but I receive an error message: “Unable to meet integration tolerances without reducing step size below smallest value allowed (3.55271e-15).“, as you can see in the below screenshot:

I’m probably doing something wrong, but couldn’t loacte it yet, the components netlists were downloaded from official manufacturer webiste (Infineon, most recent versions), and the rest of the components are ideal.

Appreciate any help!

Kind regards,

Omar

Hi Omar,

This will be impossible to debug without a simulation model as it can pertain to the parameters you’ve chosen and solver settings. Can you please share your model please?
