TPS54531: IBB capable SPICE model

Part Number: TPS54531

Can you please provide an unencrypted SPICE model of the TPS54531 that supports inverting buck boost operation?

From other E2E threads, it appears that this part will work in that mode no problem, but the SPICE model doesn't work properly probably due to some internal nodes tied in an incompatible way.

Was really hoping to feature this device is a app note that I'm working on, but I need to be able to simulate it.

Thanks!
