Other Parts Discussed in Thread: TPS54292, TPS65270
Hello,
I have been recently trying to perform simulations on TPS54291 Dual output Buck convertor. I tried simulating in LT Spice and PSpice for TI. Both the time an error appears stating that the "ERROR(ORPSIM-15113): Model MBR330 used by X_U1.D_DRIVER1_D1 is undefined". It seems like the model for the diode is missing. How do I resolve this problem.
This is the error message from the output window.

I need two outputs of 1V and 8V with a current of at least 1.5 or 2A on both outputs. My input voltage is 12V from a AC/DC switching power supply adapter. Are there any better product available to meet my required criterial? I was not able to find a suitable one from TI. Please suggest a solution for the simulation error and if available a suitable alternate IC.
Thank you. Have a nice day.
