MP1476 Simulation Support

Dear Community,
I am trying to simulate MP1476 in Pspice by importing MP1476 pspice model. Getting below error,
Kindly let me know, how can I proceed further to simulate MP1476 circuit.
Thanks in advance.

Hi preethibhat.mp,

Thank you for contacting the MPS Forum. I’m looking at your question and will work on getting you an answer soon.

Thanks,

MPS no longer supports PSpice for the MP1476 or any device. The simulation tools we suggest at this time are our own DCDC Designer or MPSmart. The advantage of DCDC designer is the ease of use of this platform while MPSmart is more powerful and faster than alternatives for our devices. I suggest downloading these tools from the product page of the MP1476 under Design Resources.

Thanks,
Brendan
