LT8711 - Buck-Boost mode

Hi,

I am trying to simulate the LT8711 as per the my application requirement for Buck-Boost operation, it working as a buck regulator but not as a boost regulator in LTspice.

Vin(min): 15V

Vin(max): 32V

Vout: 28V

Iout: 2A

F: 510KHz

I attached the schematic for your reference.

Kindly suggest for any corrections required.

Regards,

Arun
