CSD95379Q3M: SYNC-BUCK-FET-LOSS-CALC doesn't work

Part Number: CSD95379Q3M

Hi Team,

We've been trying to use the SYNC-BUCK-FET-LOSS-CALC to calculate the losses of CSD95379Q3M.

It seems like every time I press any of the '--> --> CLICK HERE <-- <--' buttons a new selection windows starts to open but closes immidiatlly without allowing the user to select the right FET.

We've been trying these on multiple computers. I've also tried to disable the macro protection in the XLS config - without luck.

Can you please advise how to make it work ?

Alternatively - is it possible to get an unlocked version of this calculator ?



  • Hi Nir,

    I tried the calculator and I didn't get any issue.

    Could you please try to follow the steps mentioned in "Intro" sheet? If you still have issue, please point out which step you had issue and what exactly the issue is?

    I don't think we are not allowed to share unlocked version, thank you for your understanding.

  • Hi Tang,

    I use the default values and just click the --> --> CLICK HERE <-- <--, a window is opened and closed immediately.

    See short video below



  • Hi Nir,

    As I understand, please follow the steps as below:

    1. Fill in all the info in step1;

    2. Click the blue button in step2;

    3. Select FET configuration in step 3a;

    4. then click button in step 3b;

    5. pick Sync FET in step 3c (there is drop down list for the FETs if you click), then you should see info for the Sync FET;

    6. Then repeat for control FET in step 3d and 3e.

    Hopefully this can solve your issue.
