Other Parts Discussed in Thread: LM2594
hello, we are experiencing problem simulating on WEBENCH a dc/dc converter with the LM2594HV. It cannot simulate (fail to simulate) a converter with a 30-45V Vin and 0,5A 12V output.
Why?

Hello Francesco,
It is incorrectly calculating the thermal of IC. Most likely using JEDEC thermal calculation
Set ambient temperature to -40 and it will compile.
These are satisfactory design conditions for this product FYI.
Hi Francesco,
We have updated the IC thetaJA of LM2594. You will able to create the design for above conditions on WEBENCH. The changes will reflect on ti.com in next release cycle by first week of October.
Thanks & Regards,
Praveen
