WEBENCH® Tools/LM76005-Q1: WEBENCH pop ups "Simulation not enabled for this design", What can I do? Want more detailed Efficiency values.

Tool/software: WEBENCH® Design Tools

Dear Sir or Madam,

regarding to use the WEBENCH I have a question about the simulation part. I have entered follow parameters :

- Vin Min = 5.7V
- Vin Max = 36V
- Vout = 3.9V
- Iout Max = 4A
- Max Ambient Temp 30°C
- ModeSetting = Auto Mode
- Set Bias Pin to Vout
- Output_CAP_TYPE = Ceramic
- User Prefered Frequency = Off
- UVLO voltage = 6.6V
- CFF Enable = Off

I get an recommended schematic. The system informations show me some values. There is a note regarding for more accurate values I should run the simulation. Especially I want to know detailed values about the "Efficiency" for different conditions (different loads, different input voltages etc.).

If i click to the buttom "SIMULATE" I get the information that "Simulation not enabled for this design". What can I do to get an simulation or more details ? Maybe it still not work because it is a new article from your site?

Thanks beforehand for your efforts.

Best regards

Wolfgang Walter

    Hello Mr. Wolfgang Walter,

    For efficiency data at different loads and other relevant information, please look for the charts tab below the schematic.

    I will soon get back to you about simulations related information. Please note, these simulations only include transient simulations such as start-up stage. line and load transients at steady state etc. Efficiency will not be a part of simulations.

    Regards,

    Hello Mr. Wolfgang Walter,

    The simulations are set to released by the end of November. I'll be closing this thread. Please reply to this thread if you have any further queries and it will reopen.

    Regards,
