LM5088* WEBANCH

Hi

Which tool are you using for the simulation ?
Are you using TI's Pspice model for the simulation ?

Regards

Hi,

Ideally you can use the MBRB2060CT diode given you have a very good layout.  Here is a diode to be considered:  STPS20M100SG-TR   (100V, 20A Schottky).

 

Hi
When using the webanch I cant modify this custom diode with the MBRB2060CT or the STPS20M100SG-TR .so how I can simulate with the webanch?

Hi Eli,

Even with the default design came with the custom diode, the WEBENCH SIMs should still work.

If you need to use exact parameters for the diode, please go to the BOM panel and select Alternate parts for D1. Once you are in the Alternate Parts Panel, at the bottom of panel, select "Create a Customer Part" and input the diode parameters.

Hope this is helpful.

Hi
With such design when you get custom device/diode, no alternate parts available at the BOM!!!
If I put the MBRB2060CT data at the "Creat Custom Part" its not working

Hi Eli,

I was able to add the parameters to create a custom diode and to run the simulation in WEBENCH.

Please note that you need to fill in all the fields including the two key parameters; Io and VRRM need to meet the WEBENCH calculated range. The MBRB2060CT parameters works except for the VRRM value has to be >78V.

Here are couple of the screen shots the procedure above.
