Simulator Comments

jsessa

While using the simulator, I cannot see, in the result, what mode I have chosen under the heatsink selection. When choosing "Variable" we get values applied for Cth, and Rth used in the resultant readout. When choosing "Fixed" those values are omitted. (?)

The WAB300M12BM3 is showing up as Obsolete. the recommended replacement is the HAS350M12BM3 however that device does not appear to be a choice in the "Devices" page pull down menu. How to add?

It is observed that the schematic diagram of the given circuit on a printed Summary report do indeed have a Schottky diode symbol being represented in the printout whereas, the diode symbols being used in the simulator just show regular diodes (am I just being picky?)

Thanks

Thank you for your post, it has been approved and we will respond as soon as possible.

Hello jsessa,

Yes, the "fixed" setting is to maintain a constant heatsink temperature therefore the option for a thermal network (C,th and R,th) for heatsink to ambient disappears as it is not needed anymore for the simulation. Please refer to the Speedfit User-guide found in the first tab of SpeedFit™ Design Simulator

It seems like HAS350M12BM3 hasn't been added to SpeedFit device list. Our team is currently working on updating it. I will provide you an update on that soon!

Which topology are you using? Thanks!

Hi jsessa,

Please use the CAS350M12BM3 to simulate the HAS350M12BM3. These modules have the same electrical and thermal performance, and therefore would not be different in SpeedFit. The difference between them is the qualification level and a few changes needed to support that difference. 

Thanks,

Blake
