LM5161: inverting buck boost simulation

Guru 20090 points
Part Number: LM5161
Other Parts Discussed in Thread: TINA-TI

Hello,

Our customer would like to simulate LM5161 inverting buck boost operation.
Their requirement is Vin=+5V, Vout=-90V, Iout=10mA.

I simulated LM5161 Vin95V, Vout,5V, Iout=10mA on the webench and export the TINA-TI file.
Then I modified the TINA-TI file to inverting buck boost topology.
However, I couldn't simulate it as I expected.

webench_design_3474743_835.tsc

Can I simulate inverting buck boost topology by TINA-TI file which was exported from Webench?
If yes, could you please let me know the wrong point in attached TINA-TI file?

I appreciate it if you support this issue.

Best Regards,
Ryuji
