TPS55340: Webench simulation for 12Vin, 38Vout, 1Aout use-case resulted output over 100V

Part Number: TPS55340

Tool/software:

Hi boost DCDC team,

One of my customer is using TPS55340 boost DCDC and want to adopt below condition to their new model and did WEBENCH simulation.

- 12Vin, 38Vout, 1Aout, (Boost DCDC)

But the WEBENCH simulation for "start up" and "stead state" resulted high Vout pulse like >100V.

They want to know if the simulation results they seen is just a "happening" due to simulator itself or if there's system impact since they are using almost maximum output rating?

Would you check and let me know this?

Best Regards,

Ernest Cho.
