Part Number: TPS54531EVM-530
Tool/software: TINA-TI or Spice Models
I am trying to simulate the circuit for TPS54531DDA from the application note slvu890 (page 15 TPS54531EVM-530) in TINA TI. But I am not getting proper voltage output during simulation. Input voltage is 28V and required output voltage is 5 volt but after Capacitor C4 (connected to pin 1 "BOOT" ) voltage drops to few mV. I tried to simulate a circuit autogenetated on WEBENCH, this circuit also not giving proper voltage output in TINA TI.
I have exported TPS54531DDA model from WEBENCH to TINA TI as TPS54531DDA spice model is nor available in TINA TI.
