LMR36510: Input transient simulation

Part Number: LMR36510

Tool/software:

Hi,
when in WEBENCH I do the input transient simulation starting from the circuit generated for:

  • LMR36510ADDAR: Input: DC 8 V - 40 V, Output: 5 V at 1 A, Temp: 30 °C and  "balanced design" 

I get the result in "WBDesign50_Input Transient-1.pdf",  4.97V<Vout<5.02V  

If in this circuit I change Cboot from Murata GRM155R71A104KA01D to Taiyo Yuden EMK107B7104KA-T and I run the simulation I get 2.49V<Vout<25.85V , see report  WBDesign50_Input Transient-2.pdf

If again I change back Cboot from Taiyo Yuden EMK107B7104KA-T to Murata GRM155R71A104KA01Dand I run the simulation I get Vout 2.49V<Vout<25.85V, see report  WBDesign50_Input Transient-3.pdf

If you also think this is a bug, please can you fix it?

Best regards,

Dino
