Hi,
It seems that LMR33610 not run on webench with the below input, why?
Hi User,
We are not able to see the attached input condition. Could you please share the same once again?
(LMR33610A or B, VinMin, VinMax, Vout, Iout, Ambient Temperature)
Thanks & Regards,

Hi User,
Thanks for your patience here. This issue is now resolved. I went ahead and created design for your input case (12V-24V to 5.00V @ 1A). Please find the same below. Hope this helps.

Hi User,
Thanks for confirmation. Could you please share the exact input case? Currently I am assuming below input case to debug this.
device: LMR33610A, VinMin = 6, VinMax=26, Vout=5, Iout=1A, Ambient Temperature=30

Hi Bhushan,
My exact requirement:
LMR33610B, VinMin = 6, VinMax=32, Vout=5, Iout=1A, Output rippleMax 75mVpp, PCB surface Temperature =70
In order to shrink the inductor and output filter i would preferre LMR33610 "B" variant.

Hi User,
For your input case, designs will fail for LMR33610B, due to IC hitting junction temperature (Effective RthetaJA = 68, this is a converter as well). Please consider changing your input case or Webench can be also used to check which parts will work for your input case. Please follow below steps for the same.
