Customer wants to use TPS54331 for Vin=15V/Vout=-5V, with Iout=1A. They tried to download the PSpice Model in ti.com to implement the simulation with SIMetrix first, but it failed to run the simulation circuits. Could you please help check whether it can work with the TPS54331 PSpice model in SIMetrix ? Could you please help suggest the example circuits for them? Thank you.
